Tom Brady's wife, Gisele Bundchen, says he has a history of concussions, including one suffered last year during the New England Patriots' run to the Super Bowl.
"He had a concussion last year. He has concussions pretty much every -- I mean, we don't talk about it. He does have concussions," Bundchen said on "CBS This Morning" on Wednesday. "I don't really think it's a healthy thing for a body to go through that kind of aggression all the time. That could not be healthy for you."
The Patriots did not list Brady as having a concussion at any point in the 2016 season.
In a statement issued later Wednesday, the NFL said records it reviewed did not indicate Brady had suffered any type of head ailment.
"We have reviewed all reports relating to Tom Brady from the unaffiliated neurotrauma consultants and certified athletic trainer spotters who worked at Patriots' home and away 2016 season games as well as club injury reports that were sent to the league office," an NFL spokesman said. "There are no records that indicate that Mr. Brady suffered a head injury or concussion, or exhibited or complained of concussion symptoms."
