The San Francisco 49ers will start Brandon Allen at quarterback Sunday against the Green Bay Packers in place of an injured Brock Purdy, coach Kyle Shanahan said Friday.
Shanahan said star defensive end Nick Bosa also will miss the game with injuries to his left hip and oblique. Left tackle Trent Williams is questionable with an ankle injury and will be a game-time decision.
This will be the first time Purdy has missed a start because of an injury since taking over as the 49ers' quarterback in December 2022.
