Indianapolis Colts linebacker Rob Morris is expected to have surgery on the knee he hurt in a win against Denver and probably will miss the rest of the season, Colts president Bill Polian said on his weekly radio show Monday.Four other Colts who were injured in Sunday's 38-20 win over the Broncos could miss the next game, which is against Tampa Bay, coach Tony Dungy said.Morris sprained his left knee late in the first half when Broncos tight end Daniel Graham was blocking him. Morris immediately fell to the ground, removed his helmet and was then taken off the field on a golf cart.Morris probably will have surgery on the knee this week, Polian said on his radio show.Dungy on Monday still was waiting for medical updates on wide receiver Marvin Harrison, safety Bob Sanders, running back Joseph Addai, backup tight end Ben Utecht and Morris."At this point, I'd have to say they all have a chance to miss some practice time or miss the (Tampa Bay) game," Dungy said. Harrison, an eight-time Pro Bowl receiver who ranks fourth on the NFL's career receptions chart, bruised his left knee against Denver and spent more than half of the game in the locker room.Sanders injured his ribs during the first half, and Dungy said team doctors told him not to play Sanders in the second half.Addai, last year's top rookie rusher, couldn't finish the game after taking a hard shot to his right shoulder. Utecht left the Broncos game with a concussion.
