Devin Singletary won't practice on Thursday due to a hamstring injury.

Devin Singletary will likely need to get in some work on Friday to have a chance to play Sunday against the Bengals. If he can't go, Frank Gore will see the bulk of the touches with T.J. Yeldon backing him up in a great matchup for running backs.

Bills are "Still gathering information" on Devin Singletary's hamstring injury. He's listed as day-to-day.

If Singletary can't go, look for Yeldon to move up to the RB2 role. So far Gore has been the main back in Buffalo.

Bills Head coach Sean McDermott says Bills pecking order at running back is: Frank Gore -> Devin Singletary -> TJ Yeldon.

Frank Gore is still the starter on paper but Devin Singletary started and outplayed the veteran by a wide margin in Week 1. Singletary will only gain work moving forward.

Devin Singletary, who changed his number from 40 to 26, showed in training camp and the preseason games many of the traits that led the Bills to select him in the third round of the draft out of Florida Atlantic. He’s quick, he has great vision, he’s tougher up the middle than you’d think for a player who stands just 5-foot-7, and he showed an ability to catch the ball.

GM Brandon Beane said one of the big things that led to the decision was that Beane couldn't help but notice Singletary every time he was on the field. The story added Singletary is not going to be an every down back, at least not yet. Gore is expected to play a significant role and Yeldon will see time on third down.

The LeSean McCoy move made it clear that Devin Singletary capably demonstrated in training camp and the preseason that he had a firm grasp of all the responsibilities required of a complete back.

“This allows Devin more opportunities to show what he can do for the team,” said Beane. “We believe in LeSean and still believe he can play, but you can’t look at every decision in a vaccum. After the draft Devin was a guy we were excited about, but some guys transition faster and some guys transition slower. That’s one of the decisions. Who is ready in that running back group to contribute right away? And we just felt right now that Devin would be able to help us along with the other guys that we’re keeping."

Other reports say Singletary won't take over the lead back role right away, he'll need to improve in pass protection and blitz pickup. He also wasn't asked to play much of a role in the passing game in college so that is a potential issue as well.

The Bills are loaded at running back, with LeSean McCoy and Frank Gore leading the way. But a rookie is getting plenty of chances to show what he can do.

Via Marcel Louis-Jacques of ESPN.com, Devin Singletary got “a ton” of first-team reps at practice on Sunday.

Singletary was a third round pick this past draft, which is significant for running backs. This is likely a case of just keeping McCoy and Gore fresh, but the story mentioned McCoy's production last season and his $6-plus million salary all leading to speculation the team could ask McCoy to take a pay cut - or possibly even move on from him.

"I wouldn't be shocked if [Devin Singletary] emerges as the most relevant running back for fantasy owners by the end of the season." "The Bills love him"

LeSean McCoy currently owns the starting gig in the Bills backfield, but he's tough to trust heading into the 2019 season. He barely cracked 500 rushing yards last year and being on the wrong side of 30 doesn't help. Drafted in the third round, Devin Singletary is actually similar to a younger McCoy is his elusive ability and could see significant playing time in Buffalo in 2019.
