Former Indianapolis Colts head coach Jim Caldwell plans to join the offensive coaching staff of the Baltimore Ravens, a league source said.

The Ravens announced last week that Cam Cameron would return as offensive coordinator, but they still need a quarterbacks coach for Joe Flacco. Caldwell now appears to be the choice.

Caldwell had visited Pittsburgh this past weekend. The Steelers are looking to replace Bruce Arians, who retired as offensive coordinator in Pittsburgh before taking the same position with the Colts.

Caldwell was fired after a 2-14 season in Indianapolis during which the team was without quarterback Peyton Manning, who missed the entire year while recovering from neck surgery.
