Redskins veterans reportedly weren’t happy upon finding out Adrian Peterson was being scratched for Sunday’s game against the Eagles, and one of them is putting Jay Gruden on notice.

“Any time you’ve got a Hall of Fame guy that doesn’t dress, man, it’s a slap in the face,” offensive tackle Morgan Moses said Monday on 106.7 The Fan’s “The Sports Junkies.”

“And obviously, we’ve gotta figure out what the reason is. And it’s my job as one of the older guys on the offensive line to speak up and say, ‘Hey, we need him,'” Moses continued. “Obviously, you don’t put a Hall of Fame guy like that on the sideline. When he’s healthy, as well.

“I think [Peterson] brings a lot to the game. I think he brings a lot to our team. But to have that guy just standing on the sideline is just, it doesn’t sit well to guys on the team or the NFL. So I think this is something we need to correct, man, because he is a helluva football player.”

Peterson was a healthy scratch in favor of Wendell Smallwood, the former Eagle the Redskins claimed off waivers who can play special teams, but the Redskins will likely need Peterson now.

The 34-year-old should get back in for Week 2 as Derrius Guice is expected to miss time with an injury to the knee he injured in college — not the knee in which he had a torn ACL last season — according to NFL Network.

Peterson helped Washington in a big way last season when Guice suffered the torn ACL and missed his entire rookie season. Peterson rushed for 1,042 yards last season with seven touchdowns, adding 20 catches for 208 yards and another TD.

“I’m 13 years in, and I’ve still got it. I’ve shown that, of course. I can play the game,” Peterson said Sunday.

Smallwood’s ability to play special teams, and Peterson and Guice both being early-down backs led to Peterson being benched, according to Gruden.

“We’re punting to Darren Spoles about five or six times. We need as many guys who can cover [as possible],” Gruden said after Sunday’s game. “We had a punt blocked and two returns on us in the preseason, so we had to get the extra linebacker up for special teams. … It had to be done.”
