And now Mike Hartline is off the board.The former Kentucky quarterback has confirmed with the UK media relations department that he has agreed to join the Indianapolis Colts as an undrafted free agent. After an up-and-down career at UK, Hartline shined in his senior season. The 6-foot-6, 206-pound gunslinger completed 268-of-405 passes last year for 3,178 yards and 23 touchdowns. The Canton, Ohio, native threw just nine interceptions.Future Hall of Fame quarterback Peyton Manning is entrenched as the starter for at least the next few years, but Hartline will have a legitimate shot to make the roster. Former Purdue quarterback Curtis Painter is currently the only other quarterback on the Colts’ roster.Hartline is the fifth Wildcat (Chris Matthews, Derrick Locke, Ricky Lumpkin and DeQuin Evans) to reportedly agree with an NFL team on Tuesday, the first day since the NFL lockout was lifted. He’ll be reunited with former UK tight end Jacob Tamme, who had a career year with 67 catches for 631 yards and four touchdowns a season ago.
