LeSean McCoy is expected to be active for the Buffalo Bills in Week 7 just days after injuring his hamstring in practice.

McCoy will at least play a limited role in the game.

McCoy has rushed 104 times for 587 yards and six touchdowns this season. McCoy had 19 carries for 140 yards and three touchdowns last week against the 49ers.

LeSean McCoy has been upgraded to a game-time decision for Week 7 against the Dolphins.

"We'll see how it goes," Rex Ryan said. "We'll be smart with him, but he looked pretty good [Friday]."

"I just felt all right," McCoy said of his return to practice Friday. "I didn't do a lot of reps today. Just was real limited, just seeing how I feel. We'll see what happens [at Saturday's walk-through practice]."

ESPN previously reported that McCoy would not play in the game.

McCoy said Friday that his injury this week was "not nearly as bad as [last year]. So that's a good thing."

LeSean McCoy will miss Week 7 after suffering an injured hamstring in Wednesday's practice.

Rex Ryan had said earlier Thursday that McCoy did not suffer a "full blown" hamstring injury and he was hopeful to have him back Sunday. 

Offensive coordinator Anthony Lynn wants to be cautious with McCoy's injury. When Lynn served as running backs coach last season, McCoy strained his hamstring in training camp and the injury lingered into the regular season.

LeSean McCoy left Wednesday's Buffalo Bills practice with a tight hamstring.

Rex Ryan wasn't aware of the severity of the injury and said McCoy would be checked out by the club's medical staff.

McCoy is the NFL's second-leading rusher with 587 yards. He has scored six touchdowns and averaged 5.6 yards per carry.

The Buffalo Bills are expected to re-sign Karlos Williams.

The Bills released the second-year running back in August.

Williams recently completed a four-game suspension.

Buffalo currently has four running backs on its 53-man roster. Mike Gillislee has taken the majority of snaps behind starter LeSean McCoy, while fifth-round rookie Jonathan Williams was active last Sunday over veteran Reggie Bush.
