Brandon Aiyuk’s NFL career has reportedly come to an end, according to SFGate. The wide receiver, once a promising star for the San Francisco 49ers, faced a decline marked by troubling behavior over the past two years, culminating in a lack of interest from other teams.
What happened
Aiyuk has exhibited increasingly erratic behavior since signing a contract extension in 2024. Following a successful 2023 season in which he amassed 1,342 receiving yards, Aiyuk suffered a knee injury that sidelined him for the rest of the season. In 2025, he virtually ghosted the team, prompting concerns among fans and analysts alike.
His social media activity further raised eyebrows. Aiyuk engaged in reckless driving, threatened to “whip the entire organization with a belt,” and openly criticized team management. He stated,
“They running from that belt that’s on the way. It’s inevitable. It’s coming. Stop running.”
Such comments, combined with his public disputes, led to his perceived unworthiness across the NFL.[3]
Why it matters
The NFL industry operates on a principle where behavior can affect a player’s career viability. Aiyuk’s actions have reportedly made him “radioactive” within league circles. Teams often overlook behavioral issues if the player is valuable enough, yet Aiyuk’s situation indicates that his actions have crossed a line, marking him as unacceptable within the league.[1]
Background
On May 10, 2024, Aiyuk signed a lucrative contract extension following his breakout season. However, by the mid-2024 season, he suffered a severe knee injury, significantly impacting his performance. By 2025, he disappeared from team activities, raising alarms about his mental health and future within the sport.[2]
What’s next
As of now, Aiyuk remains unsigned, with no NFL teams expressing interest in bringing him onto their rosters. The league’s upcoming season may see further discussions on his situation, but it appears his chances of returning to professional football are dwindling.
