Cowboys don’t believe Dunbar’s ankle injury too serious

The Dallas Cowboys don’t think Lance Dunbar’s ankle injury is serious.

They also aren’t worried about depth at running back, even with Darren McFadden sidelined with a hamstring injury.

Yet, those two situations combined only raises more questions about a running back position that was already under the microscope because of the departure of 2014 NFL leading rusher DeMarco Murray.

Dunbar underwent an MRI on Thursday. It is not known how long he will be sidelined.

“We’ll just wait and see what that MRI says,” coach Jason Garrett said. “We don’t anticipate it being bad. We just want to make sure that we get the information right on his injury and make some decisions after that.”

McFadden has been on the physically unable to perform list since the start of training camp. He has been making progress and could be back in the next few days.

“McFadden is making progress,” Garrett said. “We don’t anticipate him practicing today. We’re off tomorrow, we’ll see what we do after that, but he’s been out on the field in cleats, moving around and making progress day by day.”

Joseph Randle has handled the majority of the first-team repetitions since the start of training camp. Dunbar was having a good camp before the injury.

The injuries will allow longshot backups Lache Seastruck and Gus Johnson, an undrafted rookie out of Stephen F. Austin State, a chance to show what they can do.

“That’s what we want for every position on our team. Any time you get somebody nicked, it provides an opportunity for other guys to step up,” Garrett said. “That’s been good for them, it’s been good for us to see them, and that will continue.”

Sean Lee update

The Cowboys are taking it slowly with linebacker Sean Lee.

After missing all of last season with a torn anterior cruciate ligament, they are bringing him along in training camp with kid gloves.

Lee has been 100 percent cleared by the doctors, but the Cowboys are being cautious. He has been kept out of team drills and only recently been allowed to do 7-on-7 work.

“It’s up to the coaches, but I would expect to play a lot in the preseason,” Lee said.

Lee understands why the Cowboys are being careful. He has yet to play a full 16 games since coming to the Cowboys in the second round of the 2010 NFL Draft.

“You certainly want to be mindful of a player’s history,” Garrett said. “But I think more important than that is the recent history. Sean’s done a great job coming back off his injury.

“We have to handle it right. He’s got to handle it right and we’re confident we can do that.”

That’s what Lee wants, too.

“We’re always trying to build forward, not take any steps back,” Lee said. “That’s my goal now: Coming back, being able to stay on the field, but also producing after an injury.”
