Brett Favre talks about concussions in NBC interview

Brett Favre says he might have had "thousands" of concussions during his Hall of Fame football career.

The three-time NFL MVP who played from 1992 to 2010, including two memorable seasons with the Vikings, said Thursday on NBC's "Megyn Kelly Today" that he is experiencing short-term memory issues.

Favre, 48, said he had three or four known concussions.

"But as we're learning about concussions," he told Kelly, "there's a term we use in football and maybe other sports, that I got 'dinged.' When you have ringing of the ears, seeing stars, that is a concussion.

"If that's a concussion, then I've had hundreds, probably thousands, throughout my career, which is frightening."

Favre isn't sure it was avoidable.

"I grew up playing football," he said. "The thought process in those days was you would never come out … because you had a little head ding. You would be considered, for lack of a better term, a sissy."
