Brady: It's nobody's business but mine if I had a concussion last season

Tom Brady won't reveal whether he suffered a concussion last season because he doesn't believe it's anyone's business but his.

Speaking to reporters at New England Patriots training camp Friday, Brady wouldn't discuss his health and said that type of information is personal, according to ESPN's Mike Reiss.

The NFL, which requires players and teams to disclose concussions, would probably disagree.

Brady's wife, supermodel Gisele Bundchen, said on "CBS This Morning" in May that Brady did indeed suffer a concussion in 2016.

"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 appeared on the Patriots' injury report several times in 2016, but was never listed as having a concussion. In fact, he hasn't appeared on the injury report with a concussion in any of the past four seasons.
