Detroit Lions sign TE Cole Herdman, release LB Anthony Pittman

Earlier in the week, the Detroit Lions announced they were placing rookie tight end T.J. Hockenson on injured reserve.

On Wednesday, the Lions announced they have signed free agent TE Cole Herdman to the practice squad. In a corresponding move, they have released LB Anthony Pittman from the practice squad.

Herdman, who is a rookie, played with Lions starting quarterback David Blough last year at Purdue.
