The Colts running back situation hasn't worked out quite like the team hoped, but that doesn't mean big changes are in store. Offensive coordinator Pep Hamilton told ESPN.com Saturday he doesn't think he will change the team's rotation in the backfield, with Trent Richardson remaining the starter and Donald Brown working in as a change-of-pace back.

"We don't plan on changing our rotation with our backs," Hamilton said. "We've always been a running back by committee bunch, so we're going to continue to do that."

Richardson remains the starter, but was badly overshadowed in the team's last game against the Titans in Week 11. Brown carried the ball 14 times for 80 yards, while Richardson managed just 22 yards on eight carries.

The one mitigating factor for the Colts might be if Richardson's calf forces him into a smaller-than-expected role in Week 12 against the Cardinals. Richardson is officially questionable for Sunday's game with a calf injury.
