Singletary has been impressive in limited work for the Bills. He appeared to be in the middle of a breakout game last week against the Giants when he came up lame with a hamstring injury. In the short term, the ageless Frank Gore is set to be the main benefactor of Singletary missing time, but T.J. Yeldon could be in line for more work as well.
Hamstrings are tricky injuries, especially for running backs. This is a situation worth monitoring moving forward.
