Titans running back Travis Henry will be suspended for four games for violating the NFL's substance abuse policy, according to a broadcast report Sunday. CBS reported on its pregame show that Henry would be disciplined. A Titans spokesman said he was unaware of the situation. Phone messages left with Hadley Engelhard, Henry's agent, were not returned. Henry was the Titans' leading rusher with 97 yards and a 3.5-yard average in the first two games, and had two carries for no yards in the first half of Sunday's game against the St. Louis Rams. The Titans acquired Henry from the Bills for a third-round draft pick in July just before training camp. Henry started 48 of 53 games in four seasons with the Bills, rushing for 3,849 yards and a 4.0 yard average, and has scored 67 touchdowns.
