It's not clear which play caused the injury.
He exited the game in the first half to take x-rays in the locker room. Though the x-rays were negative, the Eagles are saying he is doubtful to return to Monday's game against the Panthers. The Eagles lead the Panthers, 15-14.
Jackson has 44 receptions for 691 yards and two receiving touchdowns on the season.
From a playoff perspective, the Eagles season is essentially over, so there's no reason to push Jackson back into the game if he is hurt.
