The Colts have signed John Navarre to challenge Jim Sorgi for the back up job in 2007. Navarre didn’t play in a game in 2006 for the Arizona Cardinals. Navarre has played in 2 games (1 start) in his NFL career and he’s completed 32 of 64 passes (50%) for 342 yards with 2 TD passes and 5 interceptions (43.9 QB Rating). This should be a spirited battle in Training Camp but look for Sorgi to prevail.
