49ers Struggle to Secure Brandon Aiyuk Amid Trade Rumors

Contract negotiations with the star wide receiver remain unresolved as the season opener approaches.

General Manager John Lynch expresses urgency in finalizing a deal with Aiyuk.
Trade discussions with the Steelers, Browns, and Patriots have not yet led to a resolution.
Aiyuk has been present at 49ers' practices but is not participating in team drills.
The wide receiver's contract stalemate is compared to Nick Bosa's prolonged negotiations last season.
Left tackle Trent Williams is also holding out for a better contract, adding to the team's challenges.
