The Colts promoted RB Darren Evans from the practice squad to the active roster on Saturday and placed WR Blair White on injured reserve.
Evans, an undrafted rookie from Virginia Tech, has played in one game this season.
White played in seven games this season. He had 36 catches for 355 yards and five touchdowns last season but does not have a catch in 2011. White injured his knee in a Week Eight game against the Titans.
White was the team's punt returner, having returned seven punts for 22 yards. Rookie Joe Lefeged has five punt returns.
