The Buffalo Bills were hoping to hear some good news regarding rookie running back Devin Singletary as the week went on, but that hasn't been the case. He has been dealing with a hamstring issue and it will cost him this week's game.

According to a report from Ian Rapoport of the NFL Network, the Bills have ruled Singletary out for this week. That means that veteran running back Frank Gore will take over as the starter against the Cincinnati Bengals.

Singletary has shown signs of being a big-time playmaker already for the Bills. In the first two games of his NFL career, Singletary has carried the football 10 times for 127 yards and a touchdown. He has also caught five passes for 28 yards.

Those numbers average out to an impressive 12.7 yards per carry. Not many rookies come into the NFL and find that kind of success.

Hamstring injuries can be a really brutal injury for running backs to battle back from. They usually don't go away completely and can pop back up later in a season. Hopefully, that won't be the case for Singletary.

All of that being said, the Bills are going to get a much better look at Gore this week. He has carried the football 30 times for 88 yards and a touchdown in two games. The numbers don't look great from a YPC perspective, but he has always been a fairly consistent running back throughout his career.

Buffalo will take on the Bengals and are hoping to stay undefeated and move to 3-0 on the season.
