The Raiders made it official on Thursday; Bruce Gradkowski’s season is indeed over because of a shoulder injury, confirming earlier reports.
Gradkowski is headed to injured reserve and an uncertain future as a free agent.
Replacing him on the roster will be a familiar face to Bay Area football fans. Former 49er J.T. O’Sullivan was signed by Oakland, and should serve as the team’s No. 3 quarterback this week against the Chargers.
