INDIANAPOLIS (AP) — The Colts have put Charlie Whitehurst on injured reserve, leaving recently signed Stephen Morris as the only healthy quarterback on the roster.

Starting quarterback Andrew Luck has already missed eight games this season and may miss this weekend's regular season finale against Tennessee. Backup quarterback Matt Hasselbeck has been knocked out of the last four games and is now doubtful after finishing Sunday's game with his injured right shoulder in a sling.

Third-stringer Charlie Whitehurst was barely able to run out the clock in Miami after hurting his hamstring.

The Colts (7-8) had former Buccaneers quarterback Josh Freeman in for a workout and that the team was now debating whether to sign him.
