The Indianapolis Colts today made a number of minor roster moves, signing free agent cornerback Chance Casey and undrafted free agent guard Will Corbin, and the team also waived-injured cornerback Josh Mitchell.
Casey was an undrafted free agent in 2013 out of Baylor, where he was a four-year starter, and was signed by the Oakland Raiders. In two years in Oakland, he appeared in four games (starting one) and recorded seven tackles and a pass defensed. He has also spent some time on the San Francisco 49ers' practice squad.
Corbin was a player who participated in the Colts' rookie mini-camp on a tryout basis, and he was impressive enough to earn a roster spot, though several weeks later. Corbin was undrafted out of Appalachian State, where he played in 35 games, starting 20. He entered college as a defensive lineman but moved to the offensive side of the football during his freshman season, when he was a redshirt.
Mitchell was signed by the Colts as an undrafted free agent shortly after the draft concluded. Mitchell played in 47 career games for Nebraska, but he apparently was injured and therefore he was waived-injured. If nobody claims him in waivers (its very unlikely that someone will), he will then revert to the Colts' injured reserve list.
The Colts had a roster spot open after waiving offensive tackle Demarco Cox last week, and they cleared another roster spot when they waived-injured Josh Mitchell. They filled those two spots by adding another offensive lineman and another cornerback, and both Will Corbin and Chance Casey will be competing trying to earn a spot.
