"It was a minor procedure. Just like a 20-minute, in-and-out cleanup of ligaments and things like that," Manuel told reporters Thursday at the Super Bowl. "So I'm happy I got it done, kinda put it past me. And obviously with the rehab and things like that, it will be back to full strength and I don't think it will bother me at all."
Manuel suffered three knee injuries during his rookie season, limiting him to 10 games. He confirmed Thursday that he tore the meniscus in his left knee in August, which required surgery and kept him out of the final two preseason games.
In a Week 5 loss to the Cleveland Browns, Manuel sprained his right knee and missed the next four games.
Entering his second season, Manuel said Thursday that he will wear a brace to protect one or both knees.
"If you look around the league, a lot of quarterbacks -- I know [Andrew] Luck wears one. Peyton [Manning] wears one, on that front leg, because you have some defenders come down and you don't want to risk getting whatever type of knee injury, so just kind of ignore it for the rest of my career," Manuel said. "I'll have a brace, but it won't inhibit me from still being able to take off and run."
Manuel finished his rookie season with 11 touchdown passes, nine interceptions, a 58.8 completion percentage and a rating of 77.7.
"They're not ACLs or MCLs, which take a year or however long to recover from," he said. "If I'm going to have a knee injury, I would rather have the ones that I had. I'd rather have them earlier, I guess, than later, to get it behind me and just start our legacy as a team and move forward."
