LeSean McCoy returned to practice Friday, but was non-committal about whether he will be ready to play in the Buffalo Bills' Sept. 13 regular-season opener against the Indianapolis Colts.
"We’ll wait and see," he said after his limited participation in the workout. "We’ll see how everything plays out. I’ve just got to control what I can control and that’s just working hard and get ready to get out there."
McCoy's return was particularly notable, given a recent ESPN report that the team was concerned his injured hamstring might be severe enough to cause him to miss the opener.
Coach Rex Ryan disputed that notion Friday.
"Apparently, that person knows more than I do," Ryan said. "… I’m hoping that he’ll be available to us and I think the only thing I mentioned" previously "was cautiously optimistic and I remain optimistic."
When informed of Ryan's remarks, McCoy said, "Me, too. Like I said, it's just a matter of time." Asked about the ESPN report, the running back said he would leave it to the coaches to address injuries.
"That's why we're working here every day, man, with the treatment and the trainers to get everything right," he said.
Rookie running back Karlos Williams also returned to practice for the first time since undergoing surgery for an unspecified issue that he said resulted from "a freak accident" and was a "very, very delicate situation."
"It felt good being out there and just being able to run around a little bit," Williams said. "Even giving a look for the defense. Being excited about football all over again. Being down, being injured for a little bit, you stay mentally into it, going to meetings, and get inside your playbook, you kind of lose that excitement almost. But watching my team the last couple of weeks I've been excited."
Williams said he "most definitely" expected to be ready for the season-opener and would contribute on special teams while trying to work himself into the running back rotation.
Besides McCoy and Williams, the Bills also are carrying Boobie Dixon and Bryce Brown and fullback Jerome Felton on their roster.
