Here's five takeaways from Redskins head coach Jay Gruden's Wednesday, Dec. 10, 2014, press conference at Redskins Park in Loudoun County, Va.:

1. Quarterback Colt McCoy "has got a chance" to play Sunday against the New York Giants.

McCoy sprained his neck midway through the fourth quarter of last Sunday's loss to the St. Louis Rams at FedExField. He's been sore and has undergone several tests since, but was able to participate in a limited role in Wednesday's practice.

"It's just a matter of getting his full range of motion back," Gruden said. "But, he did good today, and we'll get a look at him tomorrow to see if he progresses."

Gruden also gave more insight into the "kind of messed up play" that eventually knocked McCoy out of the Rams game.

"[Center] Kory [Lichtensteiger] thought he heard the quarterback say 'hut' and he didn't say it, so Kory snapped it," Gruden said. "So [Robert] Quinn had a free run at him."

McCoy tried to battle it out for a few more plays, but eventually had to exit the game. In his place, Robert Griffin III took over for the final five plays of the day for the Redskins.

Gruden said McCoy, Griffin III and third-stringer Kirk Cousins all took reps with the first team at practice on Wednesday.

"Both [Griffin III and Cousins] of them had some good plays and had some plays we've got to talk about," the first-year head coach said. "So, we're just going to get these guys reps, and it's up to them to take advantage of the reps they get. So, the decision will be made easy for us come tomorrow or Friday."

2. The injury report featured some new and familiar faces on Wednesday.

Those who did not practice included nose tackle Barry Cofield (illness), defensive end Jason Hatcher (defensive end), running back Roy Helu Jr. (toe), safety Brandon Meriweather (toe) and middle linebacker Keenan Robinson (knee).

Those limited in practice included defensive end Kedric Golston (back/foot), wide receiver DeSean Jackson (shin), tackle Morgan Moses (foot/ankle) and McCoy.

Those labeled as full participants were defensive lineman Chris Baker (chest) and linebacker Will Compton (shoulder).

Jackson – who suffered two shin contusions two weeks ago against the Colts in Indianapolis – was unable to practice or play last week. Gruden said that Jackson is able to jog, but the staff needs to see him run at full speed before they can determine whether or not he can play Sunday at MetLife Stadium.

"He needs to air it out and hopefully tomorrow he will get some more plays in practice," Gruden said. "Whether he is full speed or not, we just want to see him run. And then hopefully by Friday we can turn him up a little bit and see where he is, but he needs to be obviously full strength."

Gruden said that as of Wednesday, he felt it was a "50-50" shot Jackson would play against the Giants.

"I know that is kind of a cop out but that's kind of where he is," Gruden said.

3. A practice scuffle between wide receiver Andre Roberts and cornerback Bashaud Breeland was quickly resolved.

The two got in a little tussle after going against each other in 1-on-1 drills early in Wednesday's practice, but cooler heads eventually prevailed.

"You don't want fights at practice, but guys are a little frustrated and things happen when football players are competing," Gruden said. "I like the competitive nature of guys competing at practice, one-on-ones. We had some good, competitive team drills today, but that was a rarity. That doesn't happen very often and we addressed it."

Roberts later took to Twitter to squash the beef.

4. The various roster moves the Redskins made this week are the beginning of a continuous tinkering process.

Since Monday, the Redskins have made the following roster moves:

Signed wide receiver Rashad Ross to the practice squad. * Signed linebacker Ja'Gared Davis to the active roster from the Kansas City Chiefs' practice squad. * Waived linebackers Steve Beauharnais and Everette Brown and cornerback Greg Ducre. * Signed linebacker Trevardo Williams from their practice squad to their active roster. * Signed running back Michael Hill and linebacker Justin Jackson to the practice squad. * Signed free agent cornerback Justin Rogers to the active roster.

"We're trying to shuffle a few guys around and try and help us out on special teams a little bit – guys with some of that mentality," Gruden said. "Moving forward we're just going to continue to try to tinker with our roster."

Gruden added: "We're just trying to add players to our roster here that can help us not only this year, but in the future."

5. Asked about the work habits of his team, Gruden said "we can all study harder."

When you're 3-10, Gruden said, there's always more you can do as a team.

"I don't think we are satisfied in any part of our game right now," he said. "Our production, obviously, our preparation, we are not satisfied because we are not getting any results, so we have got to figure out a way to get the better results, obviously."

Gruden said he feels his guys study hard, but they still fall victim to some brain cramps on gamedays.

"We've got to coach better, we've got to hold these guys to a high standard and make sure it doesn't happen on a weekly basis," he said. "It seems like some of the same guys are making a mistake, might not be the same mistake but it might be a different mistake, but it's a mistake. We just got to eliminate the self-inflicted wounds."

Gruden also said, however, that studying a ton doesn't help every player.

"I've also been around some guys who don't study at all and they are very – it just comes natural to them," he said. "Some guys, football doesn't come that natural to them and they need to work harder. It works both ways."
