Colts running back James Mungro will miss the entire season after tearing a knee ligament during Sunday's preseason game against Seattle. Mungro, a short-yardage specialist who has scored 13 touchdowns in four seasons with the Colts, was placed on injured reserve Wednesday with what coach Tony Dungy said was a torn anterior cruciate ligament in his right knee. "Don't know when they're going to do the surgery but at some point that's just going to be necessary," Dungy said.
