Colts running back Trent Richardson said Thursday that he's approaching Sunday's AFC Championship Game as if he'll be the starter and added that he'll never be a healthy inactive again, the Indianapolis Star reports.

"That situation will never happen to me again," Richardson said. "Anybody can quote me, today, because it's never going to happen again."

Richardson clarified his remarks later in the report, saying that he's unsure whether he'll play against the Colts Sunday. "Whatever coach do, I'm going to agree with it, I'm going to be happy with it, because that's what's best for the team," Richardson said. "If he call me up and tell me I'm going to be playing, I'm going to be ready. If not, I'm going to be cheering my teammates on because it's their game."

The Colts traded a first-round pick for Richardson during the 2013 season. Indianapolis is a 6 1/2-point underdog against New England.
