Days after Gisele Bundchen told "CBS This Morning" that her husband, Patriots quarterback Tom Brady, suffered a concussion at some point during the 2016 season, Brady's agent said it didn't happen.

"Tom was not diagnosed with a concussion last year," Don Yee said, via ESPN's Adam Schefter. "Many of the protocols and safeguards still are evolving, and it's obviously a good thing the organization and everyone close to him is vigilant and always looking out for his health."

Hours after Bundchen's interview, the NFL released a statement saying that there was no evidence that Brady had suffered a concussion last year.

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

"We have been in contact with the NFLPA and will work together to gather more information from the club's medical staff and Mr. Brady. The health and safety of our players is our foremost priority and we want to ensure that all our players have and continue to receive the best care possible."

Here are Bundchen's original comments to CBS' Charlie Rose that precipitated a response from both the league and Brady's agent.

"I just have to say, as a wife, I'm a little bit -- as you know, it's not the most, like -- let's say, [it's] an aggressive sport. Right? Football, like, he had a concussion last year. He has concussions, pretty much. I mean, we don't talk about it," she said. "But he does have concussions. And I don't really think it's a healthy thing for your body to go through that kind of aggression, like, all the time. That cannot be healthy for you, right? And I'm planning on having him be healthy and do a lot of fun things we when are like 100 [years old], I hope."

Brady, who turns 40 in August, has said recently that he feels like he can play at least five more years.

"I always said my mid-40s," he said, "and naturally that means around 45. If I get there and I still feel like I do today, I don't see why I wouldn't want to continue."

Added bonus: Bundchen is on board with the idea -- with the obvious understanding that he takes the necessary precautions.

"She wants me to do that, too," Brady explained. "She also wants me to take good care of myself and still have my energy. My kids have grown up faster than I thought."

Meanwhile, another future Hall of Fame quarterback, Drew Brees, said that he wouldn't tell his wife if he ever suffered a concussion because he "wouldn't want her to worry."

Brees admitted that back in 2004, when he was with the Chargers, he tried to play through a concussion.

"I knew that something was not right," he said. "I knew that I was concussed. But I didn't take myself out of the game. I mean, I stayed in the game and played as long as I could until finally a coach pulled me aside and was like, 'I'm looking out for you here, and you're not gonna play anymore.' ....

"And that's why it's hard to change that mentality for guys. When you're in the heat of the moment, heat of the battle and it's competitive, you do not want to pull yourself out. That's why the concussion protocols are in place where you've got the independent neurological consultants and the trainers and the referees. Everybody's supposed to be looking."

Brees is right; players by nature are competitive. And as a result, some have hidden concussions. Seahawks cornerback Richard Sherman said he did just that during his rookie season and "it paid off."

Here's how he explained it in a story he wrote for in October 2013:

"The problem was that I couldn't see. The concussion blurred my vision and I played the next two quarters half-blind, but there was no way I was coming off the field with so much at stake. It paid off: Just as my head was clearing, Andy Dalton lobbed one up to rookie A.J. Green and I came down with my first career interception. The Legion of Boom was born."
