The Buffalo Bills list LeSean McCoy as questionable for Sunday's AFC East showdown against the Miami Dolphins with a hamstring injury, and the running back and coach Rex Ryan said a final decision on his playing status probably would be made the morning of the game.
McCoy practiced Friday for the first time since leaving Wednesday's workout early after developing tightness in his left hamstring, the same one he injured during training camp last year.
He said he "just felt all right" during Friday's session.
"I didn't do a lot of reps," McCoy said. "I just was real limited, just seeing how I feel. So we'll see what happens (Saturday)."
Asked if he felt he could play in a game, the running back said, "The biggest thing is just waiting how I feel Sunday. That's the most important. I'm doing a lot of preparation as if I'm playing, so I've just got to stay positive and keep with the treatments and being of the mind that I can go out there and play."
"We'll see how it goes," Ryan said. "We're confident in the guys that we have behind him, but not ruling Shady out at all. He looked pretty good, so we'll be smart with him. But he looked pretty good."
McCoy said the hamstring injury, which he said happened on the first play of Wednesday's individual drills, wasn't as bad as the one he suffered in 2015.
"Nearly not as bad at all," he added. "So that's a good thing."
McCoy and the Bills are balancing between risking additional injury to a player who has been instrumental in their four-game winning streak by having him play Sunday and his long-term availability.
"We'll lean on the doctors, trainers, and LeSean," Ryan said. "But Shady wants to play."
"Each day, I'm getting the treatment, the proper treatment here; the training staff's done a great job with me," McCoy said. "I'm just trying to be smart. It's a long season, but this is a game we must win."
Offensive tackle Seantrel Henderson (back) is listed as out for Sunday.
Wide receiver Robert Woods (foot) and defensive tackle Marcell Dareus (hamstring), who hasn't played all season, are listed as doubtful.
Besides McCoy, tight end Charles Clay (ankle), fullback Jerome Felton (back), offensive tackle Cordy Glenn (ankle), defensive lineman Kyle Williams (neck), center Patrick Lewis (knee), and Kevon Seymour (shoulder) are also questionable.
