Chicago Bears cornerback Charles Tillman left the field favoring his right leg in the first quarter of Sunday's game against the Indianapolis Colts.
Tillman returned to the field on the second defensive series before sitting the rest of the half. The Bears announced at the start of the second half that he would not return.
Tillman had 99 tackles and three interceptions (two returned for touchdowns) in 2011 to earn his first Pro Bowl berth.
UPDATE: Coach Lovie Smith confirmed that Tillman suffered a leg injury, adding "hopefully it's not too serious," according to Bears Radio Network sideline reporter Zach Zaidman.
