Why Does Brandon Aiyuk Owe the 49ers $13 Million?

Brandon Aiyuk owes the San Francisco 49ers roughly $13 million in forfeited bonus money, according to NFL Network insider Tom Pelissero, as the wide receiver prepares to report to the team's facility Friday afternoon in an attempt to restart his career, the New York Post reports.

Aiyuk and his agent, Drew Rosenhaus, are scheduled to arrive at the 49ers' facility at 3 p.m. Friday, according to the Post, a meeting that is expected to determine the next chapter in a relationship that unraveled over the course of the 2025 season. The money owed, and the uncertainty over how it gets resolved, now stands between Aiyuk and any path back onto an NFL roster.

How much money is at stake, and where does the $13 million figure come from?

The 49ers paid Aiyuk a $23 million signing bonus in 2024 and a $22.9 million option bonus in 2025, a combined $45.9 million in bonus money, the Post reports, citing Pelissero. Aiyuk left the team roughly three-fourths of the way through the 2025 season, triggering a 28 percent bonus forfeiture under the terms governing when a player departs mid-contract. Applied to the $45.9 million total, that forfeiture produces the approximately $13 million figure Pelissero reported.

What happens when Aiyuk reports to the facility Friday?

Aiyuk's arrival with Rosenhaus is meant to set the next steps in motion, but the bonus dispute hangs over the meeting. Pelissero described the unresolved money as "a potential complication in his efforts to secure his release by reporting to the facility Friday," according to the Post. Head coach Kyle Shanahan has not closed the door on a reunion, telling reporters, "There's no absolutes in life, so," the Post reports, language that leaves open multiple outcomes without committing the team to any of them.

Could the bonus dispute be resolved without arbitration?

The NFL Management Council and the NFL Players Association are working to resolve the situation, according to the Post. Two paths exist: the sides could reach an agreement on repayment terms, or the matter could proceed to arbitration. Either way, the Post reports the situation is complicated and may take time to produce a solution, meaning Aiyuk's on-field future could remain tied up in a financial dispute even after he reports to the facility.

What are the 49ers' options for Aiyuk going forward?

San Francisco has not announced its plans, the Post reports. The team could allow Aiyuk to rejoin the roster, release him outright, or trade him to another club. Each option carries its own calculation involving the forfeited bonus money, since how and when that $13 million gets resolved may influence whether another team is willing to take on Aiyuk's contract or wait for a release.

What else complicates Aiyuk's return?

Beyond the money, Aiyuk has an outstanding warrant for his arrest in Santa Clara, according to the Post, a legal matter separate from the contract dispute but one that adds to the uncertainty surrounding his status. The Post does not detail the underlying circumstances of the warrant, only that it exists and further complicates the broader situation between Aiyuk and the 49ers.

Key terms in the Aiyuk bonus dispute

Bonus forfeiture — A contractual provision that requires a player to repay a prorated share of signing or option bonus money if he leaves the team before the deal's term is complete. In Aiyuk's case, leaving about three-fourths through the 2025 season triggered a 28 percent forfeiture on $45.9 million in bonuses, the Post reports.

NFL Management Council — The organization that represents the 32 NFL teams in labor matters, including disputes over contract terms and bonus repayment, and that negotiates directly with the players' union.

NFL Players Association (NFLPA) — The union representing NFL players, which works opposite the Management Council on issues such as Aiyuk's bonus dispute and can pursue arbitration on a player's behalf.

Arbitration — A formal process, outlined in the collective bargaining agreement between the league and the NFLPA, in which a neutral arbitrator decides a contested financial or contractual dispute when the two sides cannot reach a negotiated agreement.

For now, the Post reports no resolution has been announced, and Friday's facility visit by Aiyuk and Rosenhaus is the next concrete event in a saga that touches contract law, team strategy, and an unrelated legal complication all at once.
