Aaron Wilson of the Houston Chronicle reports that the Colts brought in four free agent quarterbacks for workouts on Tuesday including Matt Barkley, Matt McGloin, Josh Johnson and Connor Shaw.

As of now, the Colts have yet to make a decision regarding signing any of these players.

This invites more speculation that the Colts will place QB Andrew Luck on injured reserve after his shoulder hasn’t responded as they were hoping.

Barkley, 27, is a former fourth-round pick by the Eagles of the 2013 NFL Draft. He spent two years with the Eagles before he was traded to the Cardinals in return for a seventh-round pick at the start of 2015 season.

Unfortunately, the Cardinals elected to waive Barkley coming out of the preseason last year, but he later signed on to the Bears’ practice squad before being called up a few weeks into the season.
