Bush hurt himself after recovering his muffed punt with 6:58 remaining against the San Francisco 49ers. He was tended to by trainers and then tried to walk off the field favoring his right leg. He fell back to the turf and was worked on again before being helped off the field.
There is no immediate word on the injury. Bush was taken on a cart to the locker room shortly after the injury, getting hugs from his teammates.
Bush is playing for the first time since giving back his 2005 Heisman Trophy won while at USC. The NCAA punished USC after concluding that Bush and his family took money and gifts from sports agents while Bush played for the Trojans.
He caught a 6-yard touchdown pass in the first quarter.
