Los Angeles Rams defensive lineman Aaron Donald exited Saturday's wild-card game against the Seattle Seahawks in the third quarter with a rib injury.
Donald went to the locker room twice before again returning to the sideline, but he didn't take another snap for the rest of the evening.
The six-time All-Pro racked up two sacks and three quarterback hits prior to being sidelined with the Rams up 20-13.
Donald amassed 45 tackles, 13.5 sacks, and four forced fumbles over 16 regular-season games.
The 29-year-old has led the Rams in sacks during each of the last six campaigns.
