Former QB Favre: I was concussed during '09 NFC title game

Former NFL quarterback Brett Favre told reporters during a conference call Wednesday that he played through a concussion during the 2009 NFC Championship Game against the New Orleans Saints when he was with the Minnesota Vikings.

The call took place ahead of Favre's documentary "Shocked: A Hidden Factor in the Sports Concussion Crisis," which is set to air at 6:30 p.m. ET Thursday on Stadium Network.

"A concussion doesn't necessarily have to be knocked out cold and removed from a game, although the new protocol is in place to remove you from a game even if you're not walking sideways or your arm goes stiff or whatever," Favre said.

"You may even be able to function as if you didn't have a concussion, but if you have head ringing or fireworks or any kind of fogginess, protocol says you should be removed from the game. In that game, there was some head ringing, there was some fogginess. There were two times in which I was hit by [former Saints safety] Darren Sharper late. He lunged at my head and both of them were pretty devastating hits, but I stayed in the game. One they threw a flag, one they didn't. Why they didn't throw the other, I have no idea. If head ringing or fireworks is a concussion, yeah, I did have that."

Favre said the 2009 title game was the most violent he'd ever experienced throughout his 20-year career, which he primarily spent with the Green Bay Packers. The contest went on to be part of the Saints' bounty scandal that led to coach Sean Payton being suspended an entire season after allegations that New Orleans was paying out bounties for intentionally hurting opposing players were determined by the NFL to be true.

In making his media rounds ahead of the documentary's premiere, Favre has told multiple outlets he hopes his grandsons play a safer sport than football.

"I got three grandsons," Favre said on The Rich Eisen Show. "I'm not going to encourage them to play football, I'm not going to discourage them, but I would much rather be a caddie for them in golf than watch them play football."
