Justin Durant most likely out for the season

IRVING, Texas -- An MRI exam confirmed a torn bicep in Cowboys weakside linebacker Justin Durant's right arm.

Durant suffered the injury in the second half of the Cowboys overtime loss to the Washington Redskins.

After the game, Cowboys owner/general manager Jerry Jones said Durant was out for the season. Tuesday coach Jason Garrett, as his custom, wouldn't rule out a possible return for Durant but it's doubtful he'll play the rest of this season.

There have been incidences where players didn't go on season-ending injured reserve and recovered from a torn biceps which included former Cowboys' linebacker Ken Norton Jr., and former Baltimore Ravens linebacker Ray Lewis torn his triceps in a game against the Cowboys in 2012.

Cowboys guard Brian Waters tore his triceps last season but couldn't return.

"It’s a serious injury," Garrett said of Durant. "We’ve got to see the extent of it. There are degrees to tearing a bicep. It’s a serious injury and we’re going to sort out how severe it is, what degree it is and sort out what the options are and then make our best decision."

Based on the coaches statistics, Durant leads the team with 61 total tackles and is tied with Rolando McClain with four tackles for loss.

"He played really well," Garrett said of Durant. "He was really active in the game, around the ball a lot. He played really well and take a player like that out, he makes a big difference. But the first play Kyle Wilber is in there, he makes the tackle for a one-or-two-yard gain. Those guys have played before and understand what their roles are to go in there and function. I thought he did a pretty good job."

Also starting left guard Ronald Leary suffered a pulled groin muscle late in regulation and was replaced by Mackenzy Bernadeau. Leary's playing status for Sundays game against Arizona is unknown.
