Fifteen months. That's all it took for Brandon Aiyuk to go from signing a four-year, $120 million contract extension with the San Francisco 49ers to having the team void $27 million in guaranteed money and prepare for his departure. For a player who dominated at Arizona State and seemed destined for stardom in the NFL, the spectacular collapse of his relationship with San Francisco stands as one of the most stunning contract disasters in recent memory.
This isn't just a story about an injury derailing a career. This is about how a contentious contract negotiation, missed meetings, "lack of communication," and mounting frustration on both sides turned a promising partnership into what 49ers coach Kyle Shanahan called "extremely unusual"—a situation so toxic that the team took the rare step of voiding guaranteed money just months after paying it.
The Arizona State Foundation
Before the nightmare began, there was promise. Aiyuk's path to the NFL wasn't conventional—he spent two years at Sierra College before transferring to Arizona State for his final two seasons of eligibility. But once he arrived in Tempe in 2018, he quickly proved he belonged at the highest level of college football.
As a junior in 2018, Aiyuk caught 33 passes for 474 yards and three touchdowns while adapting to the pace of Pac-12 competition. But it was his senior season in 2019 that announced him as a legitimate NFL prospect. Named First-Team All-Pac-12 as both a wide receiver and return specialist, Aiyuk exploded for 65 receptions, 1,192 receiving yards, and eight touchdowns.
His 1,192 receiving yards ranked fifth in Arizona State single-season history, and his 10.9 yards after catch per reception ranked 12th nationally. He led the Pac-12 with 3.04 yards per route run and finished second in the nation in yards after catch with 710. The Sun Devils had found themselves an elite playmaker who could beat defenses before and after the catch.

What made Aiyuk special wasn't just production—it was versatility. He amassed 2,725 all-purpose yards despite being at ASU for less than two full seasons, averaging an absurd 19.9 yards per touch in the regular season (fourth nationally). He was the only player in the country to record at least 200 yards on both punt returns (226) and kick returns (446).
"From the moment Coach Herm came to visit me, he was talking about the pro model," Aiyuk said about Arizona State coach Herm Edwards. "That's exactly what it is at Arizona State. Every practice, every week, everything that we do over there is in preparation for the NFL."
That preparation paid off when the 49ers selected Aiyuk with the 25th overall pick in the 2020 NFL Draft.
The Breakout and the Breaking Point
Aiyuk's early NFL career followed the script perfectly. After a solid rookie season, he broke out in 2022 with his first 1,000-yard campaign (1,015 yards, eight touchdowns on 78 receptions). Then in 2023, he cemented himself as the 49ers' top receiving threat with a career-best 1,342 yards on 75 catches and seven touchdowns, earning Second-Team All-Pro honors.
That success, however, set the stage for the contract dispute that would poison everything that followed.
Despite having one year remaining on his rookie deal after the 49ers picked up his fifth-year option, Aiyuk sought a new contract before the 2024 season. What followed was a contentious offseason standoff that included a trade request and nearly saw Aiyuk dealt to Pittsburgh, Cleveland, or New England at various points.
The drama dragged through the entire offseason. Aiyuk held in during training camp, refusing to practice while negotiations stalled. Trade talks intensified. Just before the Steelers trade seemed imminent, Aiyuk and Shanahan appeared to reconcile, and on August 30, 2024, the two sides agreed to a four-year, $120 million extension.
Aiyuk later admitted he made the process "a little bit more difficult than it needed to be." That may be the understatement of the year.
The Warning Signs Appeared Immediately
The ink was barely dry on Aiyuk's mega-deal when signs of discord emerged. During training camp, Shanahan and Aiyuk had a public disagreement on the practice field in which Aiyuk was told to change from red shorts into the black ones the rest of the team was wearing—a small but telling moment that suggested the relationship remained strained.
When the 2024 season began, Aiyuk struggled through the first four games, averaging just 53.2 yards per contest without a single touchdown. He appeared to be rounding into form in Week 5 with eight catches for 147 yards against Arizona, but two weeks later, disaster struck.
In Week 7 against the Kansas City Chiefs on October 20, 2024, Aiyuk suffered a devastating knee injury—torn ACL and MCL—that ended his season after just seven games. He finished the year with 25 receptions for 374 yards and zero touchdowns, a massive disappointment for a player who had just become one of the NFL's highest-paid receivers.
Had it not been for that injury, sources told ESPN, the 49ers had hoped to trade Aiyuk in the offseason. But with health concerns and his lucrative deal, a serious trade market never materialized.
The Relationship Implodes
Aiyuk was placed on the physically unable to perform list in July 2025 to begin his recovery. Coach Shanahan said in August that Aiyuk could potentially return as soon as October. October came and went. So did November. Aiyuk never returned.
Behind the scenes, the relationship was deteriorating rapidly. According to multiple reports, Aiyuk "failed to attend meetings and declined to participate in other team activities in recent months." The 49ers became particularly frustrated with his "lack of communication."
Then came the bombshell: In late July—just months after guaranteeing Aiyuk's money—the 49ers voided approximately $27 million in guaranteed money for the 2026 season. The move, first reported by The Athletic in late November, shocked the NFL.
"I've been coaching over 20 years, and I've never been in a situation where a contract's been voided," Shanahan said on November 23. "It's extremely unusual to me."
According to league sources, the 49ers voided Aiyuk's guarantees because he was not living up to the terms of his contract. His option bonus for 2026—worth $24.935 million and fully guaranteed as of April 1, 2025—was eliminated. To receive that bonus, Aiyuk's contract stated he must "adhere to all provisions of the contract, including active participation in meetings and other activities as instructed by the club."
Sources told NBC Sports Bay Area that Aiyuk incurred numerous team-imposed fines this season for his absences. When asked repeatedly about the specifics, Shanahan demurred.
"It takes a lot of things to get a contract voided," Shanahan said. "I've never dealt with that in my career and been in any building that's had that. It was unusual. But that's stuff that I can't get into right now."
The Communication Breakdown
Perhaps the most telling detail: Shanahan admitted there hadn't been "much dialogue" between him and Aiyuk throughout the ordeal. For a player and coach who once worked so closely together to develop Aiyuk into an All-Pro, the silence spoke volumes.
Aiyuk has attended workouts and rehab at the facility—Shanahan confirmed he was there as recently as late November—but he hasn't been at the portion of practice open to media in weeks and hasn't been around the locker room during media sessions.
When asked whether Aiyuk and the 49ers are on the same page regarding his efforts to return, Shanahan couldn't—or wouldn't—say. "I can't tell you that," he said.
The uncertainty extends to Aiyuk's medical status. Shanahan said the 49ers have not medically cleared him to return, but it's unclear whether that's because he's not physically ready or because the relationship has deteriorated to the point where bringing him back would be untenable.
According to The Athletic, Aiyuk told the NFL Players' Association that he didn't want to file a grievance against the 49ers for voiding his guaranteed money—a decision that suggests he may be as ready to move on as the team appears to be.
The Financial Fallout
If the 49ers do move on from Aiyuk in the offseason—which now seems inevitable—the voided guarantees provide them more cap savings, though significant dead money will remain from accelerated prorated signing and option bonuses.
An outright release with no post-June 1 designation would mean the 49ers incur a dead cap charge of $29.585 million. Beyond next season, Aiyuk is scheduled to receive base salaries of $27.274 million in 2027 and $29.15 million in 2028—money the team now almost certainly won't pay.
For Aiyuk, the financial hit is even more devastating. The $24.935 million option bonus he was guaranteed to receive? Gone. His future with the franchise that drafted him, developed him, and paid him? Over.
What Went Wrong?
How did a partnership that seemed so promising—a talented receiver from Arizona State paired with an offensive-minded coach on a perennial contender—collapse so spectacularly?
The timeline suggests the contract dispute left wounds that never healed. The drawn-out negotiation, the trade requests, the hold-in, the near-deals with other teams—all of it created resentment on both sides that the eventual agreement couldn't erase.
The public disagreement about practice attire during camp. The slow start to the season before the injury. The frustration over missed meetings and communication breakdowns during rehab. Each incident added to a relationship already poisoned by mistrust.
"What happened in July doesn't have anything to do with the future," Shanahan said, referencing the voided guarantees. "That had to do with circumstances that, to me, were out of a coach's hand."
But the carefully chosen words couldn't disguise the reality: This is a relationship beyond repair.
A Pattern Emerges?
For the 49ers, the Aiyuk situation represents the second consecutive season dealing with a player who essentially quit on the team. Last year, linebacker De'Vondre Campbell famously walked out mid-game after learning he wouldn't start following Dre Greenlaw's return from injury.
Campbell was immediately vilified. Aiyuk, interestingly, still receives support from teammates despite his prolonged absence and the voided contract. But the parallel exists: two players prioritizing their own interests over the team's, creating distractions in crucial moments.
Whether this represents an organizational problem with managing egos and expectations remains to be seen. But two consecutive years of high-profile player departures under controversial circumstances is concerning.
The Uncertain Future
Despite everything, Shanahan maintains a sliver of hope for reconciliation. "What happened in July has nothing to do with the future," he told reporters. "When it comes to the future of this, I would love for BA to be here. I would love for him to get healthy and get back to really helping us out and being part of his team. We haven't had that in a little bit, and I still hold out hope that he can get there, but he obviously hasn't gotten there yet."
General manager John Lynch echoed similar sentiments earlier this week, saying he's "definitely still hopeful" about Aiyuk's return, though he's "not counting on it."
The optimism rings hollow given the circumstances. A contract voided. Money eliminated. Communication nonexistent. Trust shattered. Even if Aiyuk physically recovers from his knee injury, the relationship appears too damaged to salvage.
The Arizona State Legacy Endures
Through all the drama, one thing remains unchanged: Aiyuk's college legacy. At Arizona State, he was everything a program could want—a dynamic playmaker who dominated in multiple facets, a hard worker who elevated from junior college to All-American, a player who embraced the pro-style system and prepared himself for the next level.
His 2,725 all-purpose yards in less than two seasons ranked fourth in school history. His 1,192 receiving yards as a senior placed him fifth on the single-season list. His 19.9 yards per touch in 2019 was a testament to his game-breaking ability.
That player still exists somewhere beneath the contract disputes and communication breakdowns. Whether he ever rediscovers that form—and where he might do it—remains one of the NFL's most intriguing questions heading into 2026.
For now, Brandon Aiyuk's NFL story serves as a cautionary tale about how quickly success can turn sour, how contract disputes can poison relationships, and how $120 million guaranteed can become worthless when trust disappears.
From Arizona State star to All-Pro to contract nightmare in less than five years. The rise was impressive. The fall has been stunning.
