Tennessee offensive tackle David Stewart suffered an apparent broken right leg on the Titans' first series Sunday against Houston.
Stewart was carted off the field by trainers, who placed the leg in an air cast. He was injured when Texans linebacker Barrett Ruud rolled onto the leg during a 26-yard run by Chris Johnson. Mike Otto came into the game as a replacement.
Stewart has started 103 games since he was drafted in 2005 out of Mississippi State.
