Waddle (undisclosed) headed to the locker room in the fourth quarter of Sunday's game against the Cardinals, Parker Gabriel of The Denver Post reports.
Waddle had his practice reps limited leading up to the game due to a chest injury. He was grabbing at his chest/shoulder area prior to exiting, per Gabriel, suggesting Waddle may have aggravated the injury as he went to the ground to avoid a fumble on a botched reverse. Prior to getting hurt, Waddle caught four of seven targets for 48 yards.
