HOUSTON - Odd move by the Colts with their offensive line: Left tackle Tony Ugoh, who's not been on the injury report all week, won't start. Ugoh missed one game with a groin injury.
Indianapolis shifts Charlie Johnson to the spot again, with Jamey Richard at Johnson's left guard spot. Rookie Mike Pollak, finally healthy, gets his first start at right guard.
There are no indications about the rationale for Ugoh to be dressed but not starting.
Johnson vs. Mario Williams will be a giant matchup right from the start.
