Long snapper Nick Sundberg said Thursday he is “100 percent” certain he will be ready to play again for the Washington Redskins when he’s eligible to be activated from the injured reserve list after missing eight games.

 “I don’t think there’s going to be any question,” Sundberg said. “I think I’ll be able to snap before the six weeks. So that’ll give me two full weeks of snapping with the guys and snapping live and things like that. I think it’s going to be good.”

The Redskins placed Sundberg on IR Tuesday, two days after he played the second half of the team’s season-opening triumph at New Orleans with a broken left arm. The Redskins signed veteran long snapper Justin Snow to replace Sundberg.

The Redskins designated Sundberg for return under a new NFL rule that allows each team to  re-activate one player per year from IR. Under the rule, Sundberg must miss at least six weeks of practices and at least eight games.

“I didn’t know I had to be out a full eight weeks,” Sundberg said. “I thought it was kind of a six-week thing. I’m very happy with their decision. I couldn’t be happier. I think it says a lot about what they think of me. At least that’s what I think.”

Sundberg said he’s been told his arm will heal in about six weeks. He might get a smaller cast after three weeks, he said. He’s not certain, he said, when doctors will allow him to resume snapping.

“That’s my question, too,” Sundberg said. “Because we have the full eight weeks, I think we’re not going to rush it. I’m not going to rush back and re-injure it or make it worse. As much as it’s killing me not snapping, I’m trying to do my best to listen to them and kind of take things slow. I haven’t not snapped for six weeks since I started snapping when I was 16.”

Sundberg said he has received “a ton” of reaction about his decision to continue playing with a broken arm.

“I’ve gotten a lot of really positive feedback,” Sundberg said. “A lot of people are saying, ‘You’re crazy. We can’t believe you’d do that. We appreciate you putting everything on the line for the team and having a real team-first attitude.’ ”

Would he do it again if given the chance?

“Yeah,” Sundberg said, “I think so. But you can say that all you want. It’s all a decision at the time about how you’re feeling and what you can really deal with.”

He also said: “The most difficult part was snapping on the sideline. On the field, it really wasn’t that big a deal because there’s so much else going on. When I’m on the sideline trying to warm up to get on the field and trying to prepare myself mentally for what I would be going through when I was actually on the field, that was the worst part because all I was thinking about was my arm and how much it hurt.

“When I got on the field, I’m thinking about the protection. I’m thinking about snapping to Sav [Rocca, the Redskins’ punter and holder for kicks]. I’m thinking about who I have to block. There were so much more things to take my mind off the pain.”
