NFL says 'no records' show that Tom Brady had a concussion

The New England Patriot's wife said her husband had a concussion last year.

"There are no records that indicate that Mr. Brady suffered a head injury or concussion, or exhibited or complained of concussion symptoms," the statement added.

The NFL said they have been in contact with the NFL Player's Association and they are working on gathering more information, adding that the "health and safety of our players is our foremost priority."

"He had a concussion last year. I mean he has concussions pretty much every ... I mean, we don't talk about it ... but he does have concussions," Bundchen said.

"I don't really think it's a healthy thing for your body to go through ... that kind of aggression all the time. That could not be healthy for you," Bundchen added.

Bundchen's comments garnered a firestorm of reaction on Twitter, and come two days after Brady said in an interview with ESPN that he hopes to continue playing football into his "mid-40s."
