Hey, so here's something fun about the NFL and head trauma.

(There is nothing fun about the NFL and head trauma).

Gisele Bündchen, famous in her own right but also married to Patriots quarterback Tom Brady, said on CBS This Morning that Brady had a concussion last year. And apparently it wasn't his first one.

"He had a concussion last year," she sad on the program in response to a question about whether she wants her husband to retire. "I mean he has concussions pretty much every — I mean we don't talk about — but he does have concussions."

So either Bündchen is mistaken about what constitutes a concussion or Brady probably has played with undisclosed concussions. Why do we know that?

Because thanks to David Woods of The Score, who went back and looked at four years of Patriots injury reports, we know Brady wasn't listed with a concussion at any point from 2013 to '16.
