The Detroit Lions signed veteran offensive lineman Leroy Harris on Monday, a move that might not be popular with everyone in the Lions' locker room. Harris drew the ire of former college and professional teammate Stephen Tulloch during last season's matchup between Detroit and Tennessee, going low on a block after the whistle. Tulloch responded by shoving Harris, netting a rare personal foul penalty for the linebacker. Harris was not flagged, but was later fined $10,000 by the league. The day after the game, Tulloch was still hot about the incident. "I didn't have anything else to say to him (after the game)," Tulloch said. "I got some other words I want to say, but I'm going to hold my tongue and keep it there." Perhaps time has healed the a wound opened in the heat of battle. Even if there is lingering animosity, don't expect Tulloch, a locker room leader, to let it impact his job. Harris has started 37 games over the past three seasons, splitting time between right and left guard. He finished last season on injured reserve after suffering a partially torn ACL. The 6-foot-3, 303-pound Harris has also played center in the NFL, but hasn't started a game at the position since 2008.
