Allen (calf) will practice Friday after being removed from the active/PUP list, JJ Stankevitz of the Colts' official site reports.
Allen sat out the first two practices of training camp due to what GM Chris Ballard described as a muscle strain in Allen's calf, but the rookie second-round pick has now been cleared for action. The 53rd overall selection out of Georgia is the favorite to start out of the gate at middle linebacker for the Colts.
