Discussing her husband's playing future in an appearance on "CBS This Morning" that aired Wednesday, Bundchen disclosed that Brady had a concussion this past season.
"He had a concussion last year," Bundchen said. "I mean he has concussions pretty much ... we don't talk about it. But he does have concussions. I don't really think it's a healthy thing for your body to go through that kind of aggression all the time. That cannot be healthy for you, right? I'm planning on having him be healthy and do a lot of fun things when we're like 100, I hope."
Brady was listed on the Patriots' injury report several times this past season, including a pair of two-week stints due to knee and thigh issues. He never appeared on the weekly report with a concussion.
In an interview with ABC News last offseason, Brady characterized concussions as a "part of life" in contact sports.
"It's just part of life, you know, not only football, but contact sports," Brady said, according to Sports Illustrated. "It's part of people walking down the street. You run, you fall, you hit your head. There's a lot of sports that are involved, but I think it's good there's more awareness than there's been in the past. Women's soccer and cycling, water polo, there's a lot of sports."
