The Buffalo Bills have been using running back Zack Moss more than Devin Singletary over the last month. During the game against the Jacksonville Jaguars, he had three carries for six yards and two catches for 18 yards before leaving in the third quarter with a head injury. They later said he is being evaluated for a concussion.
Singletary will be the primary replacement. Taiwan Jones is the only active running back beyond that, but he is a special teamer. Fullback Reggie Gilliam is also active, but Matt Breida is inactive today.
He is the second player to leave the game with a concussion after starting cornerback Taron Johnson.
Moss was the third-leading rusher on the team in terms of yards heading into Sunday. Singletary was the leading rusher followed by QB Josh Allen. Moss said coming into the league that his physicality was his best asset, saying that opposing defenders were going to “need to make a business decision” when they came to tackle him.
