The Colts worked out rookie running back Miguel Maysonet last Tuesday.
Six days later, they added the former Eagles and Browns back to their practice squad.
The Colts announced the signing of Maysonet, an undrafted free agent from Stony Brook University, on Monday.
Maysonet, 23, rushed for 30 yards on 13 carries with Cleveland in the preseason. He also caught three passes for 14 yards. The Browns waived him on August 30, one day after their exhibition finale against Chicago.
Maysonet is the lone running back on the Colts’ practice squad. The club promoted rookie Kerwynn Williams from the practice squad to the roster late last week after Vick Ballard suffered a season-ending ACL injury.
