LAKE FOREST Zach Gentry Jersey , Ill. (AP) — Bears linebacker Khalil Mack must wait until just before game time to learn if he gets a chance to rush New England Patriots quarterback Tom Brady at Soldier Field.Mack played through an ankle injury in Chicago’s last game, a 31-28 loss to Miami. On Friday, he practiced for the first time this week, although on a limited basis. Bears coach Matt Nagy says he thought Mack “moved around pretty good.”Mack is listed as questionable for Sunday. Nagy says team medical personnel will monitor how he bounces back from Friday’s practice.Mack has played in 70 straight games and has never missed a start.“That’s just who he is,” the coach said.Ultimately, the decision will depend on Mack and the medical evaluations.“When we get to the time when we’ve got to make a decision, then we’ll go with what we feel is best for him and best for the team,” Nagy said.Mack has five sacks, and last week was held without a sack for the first time this season. He didn’t comment Friday on his injury, but wants to see the Bears defense bounce back from its worst game of the year when they face the Patriots.“They’re very explosive,” Mack said. “They’ve got weapons over the top. They’ve got some good backs. And so it’s going to be a challenge.”Mack called last week’s overtime loss and 31 points allowed “difficult to handle.”Wide receiver Allen Robinson II practiced Friday on a limited basis after missing Thursday’s practice because of a groin injury. He is questionable.Cornerback Bryce Callahan is also questionable after missing Friday’s practice because of an ankle injury from Thursday’s practice. Cornerback Marcus Cooper (hamstring) is doubtful. Cornerback Prince Amukamara (hamstring) and guard Eric Kush (neck) were removed from the injury list and are expected to play. ASHBURN, Va. (AP)Fish Smithson still can’t get the number 427 out of his head. Being in the Washington Redskins’ locker room with running back Samaje Perine is one constant reminder. Smithson was a safety for Kansas in November 2014 when Oklahoma’s Perine rushed for an NCAA-record 427 yards that still stands today. ”I remember him running all over us Nick Bosa Jersey ,” Smithson said. Three years later, a season-ending injury to Rob Kelley has thrust Perine into the role of the No. 1 back for Washington. Perine has 66 carries for 210 yards through nine games, but will be expected to pick up that pace starting Sunday at the New Orleans Saints. ”With Rob’s injury now, we’ll see a lot more Samaje down the stretch here,” coach Jay Gruden said. ”I just want to see more production. That’s all.” The Redskins will split carries between Perine and third down back Chris Thompson and signed Byron Marshall off the Philadelphia Eagles’ practice squad, but this is the rookie fourth-round pick’s show now. He already has one start under his belt and felt good about getting loose with nine rushes for 35 yards against Minnesota in Week 10 when Kelley injured his left knee and ankle. But this is no cameo. Perine is now the full-time feature back, which comes with more chances on the ground and in the passing game. And quarterback Kirk Cousins believes Perine has all the tools to become a complete NFL running back. ”He’s always run the ball really hard, and I think he does a great job with that,” Cousins said. ”The pass game is really the growth that a running back needs to take when he first shows up in the NFL because of how many pressures are being thrown at them and how much responsibility we place on a running back in pass protection, and those are the places where he can grow and will grow.” Perine, whose last name is pronounced ”P-rine,” has one fumble this season that came on an exchange with Cousins. They expect that chemistry to come with more handoffs L.J. Collier Jersey , as will the 22-year-old’s familiarity with the offense, blocking schemes and opposing defenses. ”You just have to get the reps, and once the reps build up and once you get more comfortable in the situation then things start to slow down for you,” Perine said Wednesday. ”It takes actual game reps. And you can practice it all you want, you can look over film, but actually getting those full-speed reps that’s really going to help when it comes to knowing how the speed is and how everything is put together.” At 236 pounds, Gruden said the Redskins would like to see Perine run over more defenders, break more tackles and pile up some more yards after contact. That would help their 23rd-ranked running game, which hasn’t been able to keep enough opposing defenses honest. As Gruden has grappled with staying committed to the run and abandoning it for pass-happy drives, Perine should help significantly because of the type of back he is. ”He’s such a physical guy that I think the more carries he gets, he’ll wear down a defense,” Gruden said. ”He’s not so much a spell guy Marquise Blair Jersey , he’s more of a run it, run it, run it type guy.” Smithson knows all about that. The practice-squad safety actually made the tackle on Perine’s record-setting run and recalls the game coming to a stop for a few minutes as fans gave a standing ovation. It’s one of his ”worst memories,” but now it gives him confidence that Perine can do the job. ”That just shows how much potential he has,” Smithson said. ”He was a great back at Oklahoma. He’s having a good year now, and I feel like now that he’s getting a good chunk of the load, he wants to prove what he can do.” NOTES: WR Terrelle Pryor did not practice Thursday with an ankle injury after undergoing an MRI. TE Jordan Reed (hamstring), LT Trent Williams (knee) and C Spencer Long (knees) also did not participate. … The team put OT T.J. Clemmings on injured reserve with an ankle injury and brought back OL Tyler Catalina. —
