The Washington Redskins will be without cornerback Fabian Moreau and slot receiver Trey Quinn when they visit the Atlanta Falcons on Thursday for their third preseason game, and running back Derrius Guice’s availability remains uncertain.

Moreau missed all three practices this week with an ankle injury, which probably means increased playing time for Greg Stroman and Jimmy Moreland. Moreau was seen riding a medical scooter in the team facility Tuesday.

Quinn has been practicing and said he would play if it were a regular season game. He injured a thumb in a collision during pregame warmups for the preseason opener at Cleveland while trying to catch a punt. Quinn hopes to be available for the final preseason game against the Baltimore Ravens next week.

“It kind of sucks. I want to get out there and play,” Quinn said. “But it’s progressing well. It should be healthy pretty soon. … This isn’t a big thing. I’d go out there and fight tomorrow with my brothers. It’s their decision to keep me out. I like reps; I love football. I don’t need them, but I want them. I get aggravated not being out there."

The status of Guice, the second-year running back who tore his left ACL in the team’s first preseason game last year, remains uncertain. He has yet to be medically cleared for game action, but Coach Jay Gruden said he’s “pretty confident that he has a chance to go.” Gruden didn’t rule out playing Guice in Washington’s final preseason game if he can’t play Thursday.

“It’s important for him to get a couple carries, just get the feel of getting tackled again,” Gruden said. “Would love to see that happen. Coming off an injury, I don’t want the first carry for him to be against Philadelphia [in the regular season opener]. I’d like to get him a couple carries, get a little sweat going, feel the contact and get used to getting taken to the ground, protecting the football.”

Tight end Jordan Reed will be a game-time decision Thursday, and wide receiver Paul Richardson Jr. “probably” won’t play, Gruden said. He expects the starters to play about a quarter and a half against the Falcons or, at most, the entire first half.

Tim Settle (knee) and Caleb Brantley (groin) returned to practice Tuesday, a good sign for a defensive line that was getting thin with injuries. Gruden said Brantley participated in individual drills and Settle did a little more. Both are game-time decisions Thursday.

“It’s a great rotation once we get Caleb healthy and Settle back healthy,” Gruden said. “Some other guys have started to emerge a little bit, possibly a sixth or seventh guy. Those guys are fun to watch.”

Quarterback Colt McCoy remained out of practice, as expected, with complications from his broken right leg that Gruden said could linger a couple of weeks into the season.
