San Francisco 49ers quarterback Brandon Allen has an injury on his left middle finger, with team photos showing him wearing a wrap before Sunday's game.

Brandon Allen was a three-year starter at Arkansas and led the Razorbacks to bowl victories in his redshirt junior and senior seasons. Former Wisconsin Badgers head coach Bret Bielema coached Allen in the quarterback's final three years at Arkansas.
