Allen (knee) was ruled out for Sunday's game against the Cowboys, The Team 980 reports.

EDGE Analysis

Allen suffered the left MCL sprain in the season opener and was a non-participant at practice Wednesday and Thursday, so it's not a major surprise he won't be playing Sunday. Treyvon Hester figures to see an increased role in his absence, especially if Caleb Brantley (ankle) is also ruled out.
