It’s been nearly three years since Russell Wilson first made headlines for claiming he solved a concussion with water — a claim that has no scientific backing and is honestly pretty terrible to say in an age where so many people are trying to figure out a way to stop NFL player and other athletes from suffering from the terrible things that come with repeated head trauma and multiple concussions.

But, apparently people are still buying his claims.

Including, according to the New York Times, the Yankees’ Clint Frazier, who was experiencing concussion symptoms this week after a collision with the wall.

From the New York Times:

Then, on the advice of Russell Wilson, the Seattle Seahawks quarterback who is in camp this week with the Yankees, Frazier began drinking water — and lots of it.

Frazier guzzled six 12-ounce bottles over an hour or so Wednesday morning, and suddenly the symptoms diminished. His headache dissipated and his hunger returned.

“I don’t know for sure,” Frazier said with a laugh, estimating that he had drank a gallon of water. “But it pumps oxygen to your brain a lot, so I feel alive right now. Maybe I was lacking water; I don’t know. Maybe I just feel good.”

Of course there’s nothing bad about drinking water. Everyone should be hydrated! But there’s no evidence it helps concussions — or (and we’re looking at you Tom Brady) is a replacement for sunscreen.

Even Wilson at one point sort of seemed to know this. Or at least know well enough to say it.

After the backlash to his claims in 2015, he clarified to ESPN that he wasn’t actually diagnosed with a concussion — meaning that his Recovery Water didn’t cure any sort of head injury.

“I didn’t have a concussion,” he 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.’”

According to the Times, Frazier was seen by a doctor outside of the Yankees organization and avoided most baseball activities. He credited the water with helping him feel better when he started to feel better nearly five days after suffering the injury.
