Erik Walden, who head butted Titans tight end Delanie Walker in Thursday's 30-27 Colts win, was suspended one game, according to Fox Sports' Jay Glazer.
Walker wasn't wearing a helmet at the time because Walden ripped it off by his face mask during the play. Walden was given an unnecessary roughness penalty but wasn't ejected.
Walden, a seventh-year player out of Middle Tennessee State who has 28 tackles, two sacks and a forced fumble this season, has the right to appeal, so he could play in Sunday's game in Arizona and miss the rematch with the Titans in two weeks.
