Seattle Seahawks quarterback Russell Wilson said Thursday he did not suffer a concussion in the NFC championship game against Green Bay, a day after comments in an article in Rolling Stone indicated Wilson may have suffered a head injury.

Wilson says that his comments were misunderstood and he did not have a head injury. Wilson took a big hit in the first half of the championship game from Green Bay's Clay Matthews following an interception. Wilson remained in the game and led Seattle's late comeback for a 28-22 overtime win over the Packers.

In the Rolling Stone article, Wilson raves about a product called Reliant Recovery Water -- based in nearby Tacoma, Washington -- of which Wilson is an investor. "I banged my head during the Packers game in the playoffs, and the next day I was fine. It was the water," Wilson was quoted as saying in the article.

After Seattle wrapped up its final full practice before its third preseason game at San Diego on Saturday, Wilson clarified what he was trying to convey.

"No, I didn't have a concussion. I guess it was perceived wrong. But no, I did not have a concussion," Wilson said. "I was saying that I had been consistently drinking the water for a month, month-and-a-half five to seven times a day and I was thinking, `Maybe this stuff is helping me out.'"

Wilson added that some of his teammates -- mentioning Kam Chancellor and Russell Okung specifically -- have used the product.

"It's one of those things that I truly do believe it helps with recovery," Wilson said. "It's one of those things, the science behind it, all that help they're trying to do, I've been down to the laboratory in Tacoma and it's pretty amazing to see everything that is going into it. It's going to be a special company, I really believe in that."
