With LeSean McCoy still nursing a hamstring injury and backup RB Karlos Williams sustaining a concussion in last week's game, the Bills took steps Tuesday to bolster their running back corps signing free agent Dan 'Boom' Herron.
Herron worked out for the club Tuesday morning along with a few other free agent backs, before he was signed early in the afternoon.
He comes to Buffalo after spending the last two seasons with the Indianapolis Colts. Herron sustained an injury in the preseason and the Colts placed him on injured reserve. Indianapolis released him from I-R four days later.
Herron has played in 25 career games, starting three, and racking up 389 yards and one touchdown on 87 carries. He has also caught 22 passes for 230 yards. The 26-year old originally entered the league as a sixth round pick (191st overall) of the Cincinnati Bengals in the 2012 NFL Draft.
To make room for Herron on the 53-man roster the Bills placed TE MarQueis Gray on injured reserve. Gray suffered a fractured forearm in last Sunday's game against the Giants.
Buffalo also signed WR Walter Powell to the team's practice squad.
Powell joins the Bills after being released from the New York Jets practice squad on October 5. The 6-0, 189 pound Murray State product has appeared in four games, mostly as a return specialist. For his career, he has 12 punt returns for 48 yards and eight kickoff returns for 233 yards. He originally entered the league as a sixth round (196th overall) draft pick by the Arizona Cardinals in 2014.
