Addison exited Thursday's game against the 49ers and headed toward the locker room after suffering an apparent foot injury, Tom Pelissero of NFL Network reports.
Addison was able to walk to the locker room under his own power. The rookie was enjoying a career game before exiting with six receptions for 110 yards and two trips to the end zone. It remains to be seen what his status will be for the remainder of the game.
