Bills sign RB Boom Herron, place TE MarQueis Gray on IR

The Buffalo Bills hosted Trent Richardson, Dan "Boom" Herron, and several other running backs for workouts on Tuesday in light of Karlos Williams' recent concussion.

After the workout, the Bills announced that they have signed Herron.

Herron last played for the Indianapolis Colts in 2014 when he started three games and rushed for 351 yards on 78 carries. He was waived by the Colts in September due to a shoulder injury. With Williams' status uncertain for Week 5, Herron is a candidate to play on Sunday.

To make room for Herron, the Bills placed tight end MarQueis Gray on injured reserve after suffering a fractured forearm in Week 4.
