"When members of the union that is in place to help players is lying/withholding information from a player on behalf of the team alongside a certified agent.. That's some straight BS!!!" Aiyuk wrote on Instagram.
"Some players have no other place to go for information or help, and are relying on the union to help them continue advancing in their careers and lives!
"I'm sure there are great members of the union, so this message does not pertain to them but about the ones in my specific case."
Aiyuk's latest criticism comes after he blasted the 49ers, calling general manager John Lynch "creepy" and comparing head coach Kyle Shanahan's temperament to that of a "toddler," which, at this point, seems ironic to most.
The wide receiver also recently claimed he had cut ties with his agent, Ryan Williams of Athletes First, in November 2025 by terminating his Standard Representation Agreement (SRA). However, NFLPA records later revealed that the agreement wasn't officially terminated until Saturday. Those same records now list Aiyuk as unrepresented.
Aiyuk suffered ACL and MCL injuries during the 2024 season after signing a four-year, $120 million contract extension. During his rehabilitation, a rift developed between the receiver and the 49ers, ultimately leading the team to void his guaranteed money. A frustrated Aiyuk did not fight the move but cut off communication with the organization.
The 49ers later placed Aiyuk on the reserve/left squad list, ending any chance of him returning during the 2025 season. He has reportedly still not filed the paperwork required for reinstatement.
According to multiple reports, Aiyuk's standing around the league has deteriorated to the point where he is widely viewed as untradeable. His most realistic path back to the NFL may be waiting for his eventual release and hoping a team—such as the Washington Commanders—is willing to offer him a low-risk, one-year prove-it contract.
