Washington Redskins running back Adrian Peterson has had a nice comeback this season and is a big reason the team is having so much success. The second half of his season is going to be more challenging with three starters injured.

The Redskins will take on the Tampa Bay Buccaneers on Sunday without Trent Williams, Shawn Lauvao, and Brandon Scherff. Right tackle Morgan Moses also didn't practice and it's unclear if he will start on Sunday. Peterson knows running the ball is going to get tougher, but he is trying to stay upbeat.

“You've just got to stay positive and keep pressing,” said Peterson per John Keim of ESPN. “It's not the end of the world, and it's not the end of the season for us. We all have to perform better. That's the mindset that I have. … There's something different when you lose three starters to where your mindset shifts to, ‘I just gotta do more than what I was doing before.'”

Coach Jay Gruden also tried to downplay the injuries saying Peterson is still the same back no matter who is front of him, and he just needs to go through his reads like he normally would.

“He just goes through his reads like he normally would,” Redskins coach Jay Gruden said. “It doesn't matter who's blocking for him — at guard, center, tackle, tight end, fullback — if we had one — or receiver. He's just going to go through his progressions and make his cuts and do what he does. It doesn't matter.”

Peterson, who's fifth in the league in rushing with 604 yards, was kept in check last time out by the Atlanta Falcons as he had just 17 yards. Hopefully, he can bounce back against the Buccaneers' subpar run defense even with a reshuffled O-line in front of him.
