Jan 3 (Reuters) - The Buffalo Bills could be without their best offensive weapon when they play their first playoff game in 18 years on Sunday as injured running back LeSean McCoy sat out practice on Wednesday.
The centerpiece of the Bills' offense injured his ankle in Sunday's regular season finale and his status ahead of the wild-card clash against the Jacksonville Jaguars was listed as "day-to-day" by Buffalo head coach Sean McDermott.
"He's a fierce competitor," McDermott told reporters. "He's hard at work; maximizing the treatment opportunities to get himself to where he can play."
McCoy was hurt during the third quarter of Sunday's game. After being tackled, McCoy pounded the turf in frustration while being attended to by trainers. He was carted off the field and was in a walking boot and tears after the game.
The Bills, who on Sunday will be appearing in their first playoff game since January 2000, could be forced to rely heavily on Marcus Murphy and Mike Tolbert, who shared carries after McCoy went down.
"Next man up. That's what we’ve done all year," said McDermott. "You never replace a player like LeSean.
"I've got a lot of confidence in Mike Tolbert and Murph and whoever else we put in the backfield. They did a nice job this past weekend and I expect them to do the same moving forward." (Reporting by Frank Pingue in Toronto, editing by Ed Osmond)
