PHILADELPHIA (973espn.com) - Both the NFL and DeMarco Murray are a little unsure about Sunday's game against the Redskins.

The league is concerned about Hurricane Joaquin's effect on the Landover area but even if the Super Doppler gives the all clear, the embattled Eagles running back hasn't committed to playing on what could be a muddy track.

Murray, who was managed just 11 yards on 21 carries in two games this season, was a full participant at practice Thursday, a day after being limited so things are trending in a positive direction but the reigning rushing king still isn't sure his hamstring will be strong enough to deal with a powerful Washington run defense.

"I feel good," Murray said at his locker after practice. "We'll see how it goes. It felt better today. I made some progressions, and we'll see Sunday."

Murray, of course, missed last week's win over the New York Jets while dealing with the hamstring injury and his understudy, Ryan Mathews, cracked the century mark with 108 yards on 24 carries, numbers Philadelphia expected from Murray after signing the ex-Cowboy to a big money deal in the offseason.

"Whenever you miss a game, it kind of kills you a little bit," Murray said before explaining the success the offense had without him.

"I thought they were able to get some creases going," he continued. "I thought they blocked it very well. We had a good game plan. I thought Ryan did a good job running through some (holes) and making some good reads. The blocking was better. Obviously he was able to get some things going. He ran well. They blocked well."

Murray also discussed his own struggles before he tweaked the hamstring at practice last week.

"I just think we've got to continue to create more opportunities," the 2014 All-Pro said. "The first two games didn't go according to what we wanted. We can learn from those mistakes we all made and just continue to grow from the last game we played."

With Joaquin on a track that could effect much of the Mid-Atlantic region by game time Sunday Murray realizes conditions could be spotty.

"As a running back you kind of look forward to those games because you know you'll probably get a lot of carries," he said, "I'm sure we'll be able to weather the storm."

Will "we" include DeMarco, though?

"As a competitor, you want to be out there practicing every day. You want to be out there playing a game every opportunity you get. I'm definitely excited to get back out there if I can."
