The veteran told NFL Media's Nate Burleson at Monday's Opening Night that he plans to play in Super Bowl 50.
"I feel great," Allen said. "Honestly, I feel, hopefully, I'll be a tremendous factor in this game. So, as far as physically, 100 percent ready to go, just preparing like normal."
Allen participated in practice on Monday, along with the rest of the Panthers. Rivera slow played any decision on the pass rusher, saying Allen will have to make it through the week in order to see the field.
"He gets rid of the ball so fast, he's so smart, he knows where the ball is going before he even snaps the ball. So, I've hit him a bunch of times, that counts, right?" Allen said laughing.
Even a diminished Allen will be a boost when the Panthers get after Manning with a Lombardi Trophy on the line.
