The team also waived-injured cornerback Josh Mitchell. If Mitchell clears waivers, he will revert to the team’s Injured Reserve list.
A roster spot was available after the Colts waived offensive tackle Demarco Cox last week. Cox was a former college basketball player who received a look during offseason training activities.
Casey, 5-11 and 190 pounds, originally signed with the Oakland Raiders after going undrafted out of Baylor in 2013. He played in four games (one start) in two seasons with the Raiders and registered seven tackles (six solo) and one pass defensed. Casey also spent time on the San Francisco 49ers practice squad in 2014.
Casey was a four-year starter at Baylor at defensive back. He played in 43 games (33 starts) and finished with 212 tackles, 21 passes defensed and three interceptions. Casey was a member of a senior class that played in three straight bowl games for the first time in school history and won back-to-back bowl games for the first time since 1985-86. The dual-sport athlete earned All-Big 12 freshman honors in football and All-Big 12 honors as a hurdler for the Bears track team as a sophomore.
Corbin, 6-6 and 305 pounds, worked out with the Colts on a tryout basis during the recent three-day rookie mini-camp after going undrafted out of Appalachian State. He played in 35 games (20 starts) over his five years as a Mountaineer. Corbin began his collegiate career on the defensive line before making the transition to offensive line during his redshirt-freshman season.
Mitchell, 5-9 and 173 pounds, originally signed with the Colts as an undrafted free agent on May 4. He played in 47 games at Nebraska and finished with 104 tackles (79 solo), 3.0 sacks, three interceptions and 25 passes defensed.
The team is currently working out in voluntary OTAs and will continue through mandatory veteran mini-camp June 8-11.
