Wallace (knee) didn't participate in Cleveland's practice Tuesday, Daniel Oyefusi of ESPN.com reports.
Wallace is in danger of missing Thursday's matchup versus the Steelers, as he was also listed as a non-participant in Monday's practice estimate after suffering a knee injury during the Week 3 win over Carolina. Isaiah Bond and Malachi Corley could be in line for increased playing time if Wallace is unable to suit up for Thursday's game.
