Indianapolis Colts quarterback Peyton Manning looks on in the second half of an NFL football game against the Baltimore Ravens in Baltimore, Sunday, Dec. 11, 2011. Baltimore won 24-10.

INDIANAPOLIS — Peyton Manning has started throwing the football again.

Colts coach Jim Caldwell said Wednesday that Manning is throwing the ball as part of his rehabilitation from neck surgery Sept. 8. There's no indication that Manning will practice with his teammates before the season ends Jan. 1, much less play in a game, but the news was a positive step in Manning's recovery.

The Colts are 0-13 this season and Manning hasn't played a down as he recovers from his third neck surgery in a span of 19 months. Doctors cleared him to start throwing the ball earlier this month.
