He left last week's game very early with a hamstring injury. He didn't practice on Wednesday, but participating in practice the last two days has earned LeSean McCoy the designation of questionable for Sunday's game against the Lions.
McCoy was limited in practice on both Thursday and Friday.
"I did some things," McCoy said. "It felt good to be out there with my teammates, getting loose, feeling comfortable again."
On pace for the least productive season of his career, McCoy said his hamstring just felt tight last week and there was some soreness.
"It's just a part of the game, but it's the frustrating part," he said. "Just how the season has gone. We had a lot of expectations for our season. You have to control what you can control and keep pushing and keep fighting."
With a questionable designation, and the playoffs no longer part of the equation for Buffalo, the question was posed to head coach Sean McDermott if he'd consider sitting McCoy even if he might be able to play, but not 100 percent and take a look at young players like practice squad call-up Keith Ford.
"At the end of the day it's going to be about his availability, but we take that into consideration in terms of wanting to see more of the young players, Keith Ford being one of them," McDermott said. "We'll weigh all of that as we make our decisions for game time."
"I could use some more yards," said McCoy. "Any opportunity I get to do that, I love it."
Fellow RB Chris Ivory was also listed as questionable despite being a full participant in practice all week.
Meanwhile K Stephen Hauschka practiced for the first time on Friday on a limited basis and though listed as questionable is expected to kick for the Bills on Sunday.
