Coach Dan Quinn announced Thursday that the third-rounder slipped in the shower and hit his head on Wednesday, leaving Coleman mired in the league's concussion protocol, per The Atlanta Journal-Constitution.
Depending on the severity, it's fair to wonder if Coleman will play again this season for a Falcons team in complete freefall.
Other injuries we've been tracking on Thursday:
- The Chargers suffered several injuries during Thursday's 23-20 overtime loss to the Raiders. Cornerback Jason Verrett (hamstring) and safety Eric Weddle (groin) made early exits and guard Orlando Franklin left in the second half to be evaluated for a possible concussion. In the first half, Chargers safety Darrell Stuckey suffered a knee injury and didn't return.
