INDIANAPOLIS - An already improving Colts defense is adding linebacker Robert Mathis back into the mix.
The four-time Pro Bowl player expects to play Sunday against Miami after missing the previous three games with a knee injury.
Mathis has five sacks in four games this season. He got a limited number of snaps in practice Wednesday, but doesn't expect any limitations Sunday.
Mathis is one of several Colts who have dealt with injuries this season. Defensive end Cory Redding and outside linebacker Dwight Freeney have both returned from injuries. So has inside linebacker Pat Angerer.
Even with the adjustments the coaching staff has been forced to make, the defense has allowed just 26 points combined in wins over Cleveland and Tennessee the past two weeks.
