RENTON, Wash. -- Russell Wilson clarified Thursday that he didn't suffer a concussion in the NFC Championship Game, expanding on comments he made to Rolling Stone about how he believes a brand of water helped him during last year's postseason.

The Seattle Seahawks quarterback told the magazine that he banged his head in the NFC title game against the Green Bay Packers but felt fine the next day because of Reliant Recovery Water, in which he is an investor. After Thursday's practice, Wilson clarified that he believes the water helped him prevent an injury, not recover from one.

"I didn't have a concussion," Wilson said. "I guess it was perceived wrong. I did not have a concussion. I was saying that I had been consistently drinking the water for a month and a half -- five, seven times a day. And I was like, 'Man, maybe this stuff is helping me out.'"

Wilson said teammates like Kam Chancellor and Russell Okung also use the water.

"I didn't have a head injury, but what I was trying to say is I think it helped prevent it," he said. "I think your brain consists of like 75, 80 percent water, so I think that just being hydrated, drinking the recovery water really does help."
