"It's an old injury he'd been dealing with, he'd been fighting through for years," Rivera said. "The surgery is going to fix it. It's going to repair it. It's going to put it in better shape than it has been. Cam is going to play the way he plays. He's going to play to his ability, the best of it.
"Is there a thought you have to be careful with him?" Rivera continued. "Yeah, but you know if this surgery is going to make it better than it has been in a long time, you want him to play the game the way he plays it best."
Some other takeaways from the press conference, which featured both Rivera and general manager Dave Gettleman:
"The players we brought in, and again I know it's not sexy, but often times the answers are on your roster," Gettleman said. "And we have a couple younger guys that we have confidence in terms of them becoming contributors. So we're happy where we're at."
"Other than the QB, there's five other players that can make plays for you," he said. "And I think right now what we've done is bring in guys who have the ability to make plays for us. I feel very comfortable with that. We've got to be able to replace 10 catches a game on the average by the wide receiver position. How explosive those plays are will determine the types of players we have on the field."
» Gettleman said he's given first-round grades to nine or 10 wide receivers and offensive tackles. Call it a major upset if one of those positions aren't addressed with the Panthers' first pick (28th overall).
