Detroit Lions promote Rodney Austin, cut Kellen Davis

ALLEN PARK, Mich. -- In an attempt to bolster the depth on a beaten-up offensive line, the Detroit Lions have promoted offensive lineman Rodney Austin from the practice squad to the 53-man roster for the second straight season.

Promoting Austin had been considered after Larry Warford was injured against Miami, but the Lions chose to stick with their roster makeup against Arizona and New England due to health issues at other positions. With Detroit mostly healthy otherwise -- including at tight end -- the Lions had the flexibility to make a move and did, cutting Kellen Davis.

Other than at offensive line, the Lions looked fairly healthy at practice. Besides Warford, left tackle Riley Reiff (knee) missed practice and his status is in doubt for Thursday's game against Chicago. Also missing practice Tuesday was defensive tackle Nick Fairley.

Davis was initially signed prior to the team's London trip.

Detroit also re-signed linebacker Jerrell Harris to the practice squad. He had been with the team earlier this season.
