Brett Favre took a lot of big hits over the course of his lengthy professional career.

Brett Favre was hit with a number of major hits in the span of his long professional career.

Although this Hall of Fame quarterback sustained only a few official concussions in his career, he believes the real number is much greater.

Favre admitted that the NFL legend believes that he sustained many concussions in the time during the course of his NFL career.

If this is the case, then I hope Favre is doing all possible to protect his brain when he retires.

"Concussions happen all the time," Favre said on The Bubba Army radio show. "You get tackled and your head hits the turf, you see flashes of light or ringing in your ears but you're able to play -- that's a concussion."

"So, based on that, [I've suffered] thousands," said he went on. "Had to be, because every time my head hit the turf, there was ringing or stars going, flash bulbs ... but I was still able to play."

"Brett had close to 11k attempts through the 90's and 2000s NFL getting sacked over 500 times so he might be right," one fan wrote via social networks.
