The Colts have made several minor moves, including the signing of cornerback Chance Casey and guard Will Corbin, per Indysportscentral.com. They have also waived-injured cornerback Josh Mitchell.
Casey has played in four NFL games in two seasons. He totaled six tackles with Oakland a year ago.
Corbin and Mitchell are undrafted rookie free agents. If the latter clears waivers, he will revert to injured reserve.
