Harrison doesn't make trip with Colts, out with hamstring injury

INDIANAPOLIS -- Colts wide receiver Marvin Harrison will not play Thursday night at Jacksonville because of an apparent hamstring injury.

Colts spokesman Craig Kelley said Harrison didn't travel with the team when it left for Jacksonville on Wednesday. Earlier, coach Tony Dungy said Harrison underwent an MRI exam and would be questionable for the game against the Jaguars.

Harrison might not be the only key Indianapolis player missing from Thursday night's game. The availability of running back Joseph Addai and safety Bob Sanders likely will be gametime decisions, Dungy said.

Addai has been nursing a sore shoulder, which he injured Dec. 7 against Cincinnati, and didn't play Sunday against Detroit. Sanders, whose right knee was swollen last month, also was held out of the Lions game.

Addai and Sanders were among 12 players the Colts listed as questionable Wednesday.

Dungy said both players have practiced with the team this week and want to play.

"They're excited about going. My sense is they'll play, but we'll see what happens," Dungy said. "We probably won't know until game time. It's going to be one of those things we'll probably have to wait and see."
