Bradford, favoring his left arm, walked off the field and into the locker room after a Chris McCain strip-sack in the third quarter. It was the fourth sack of the game for the Dolphins. Bradford was also slow to get up late in the first half after a roughing the passer penalty.
Howard Eskin of Fox 29 Philadelphia reported Bradford had trouble remembering the first half of the game, and that his status for next week was uncertain.
Mark Sanchez replaced Bradford and converted a third down on his first play.
Bradford is in the last year of his contract and first season with Philadelphia. Entering Sunday, he had completed 62.9% of his passes with 10 touchdowns and 10 interceptions for a 79.5 passer rating.
