It turned out the nondescript liquid Hill was sipping was pickle juice, Patrick Mahomes told 610 Sports Radio in Kansas City on Monday.

"That was the ol' pickle juice, man," Mahomes said. "You know, he was cramping up a little bit, so you gotta give him the pickle juice to get him back to the 'cheetah,' you know what I mean?"

Mahomes said that the pickle juice is to prevent cramping.

"Well, the pickle juice usually is before, like to try to keep you from cramping," Mahomes said. "I don't know... might have to do with the sodium, I think. They try to keep you from cramping. I think he had... the full cramps already, so they had to use the full IV."

"Some athletes swear by pickle juice as a fast way to stop a muscle cramp. They believe it’s effective because of the high water and sodium content. But that might not be the case. While pickle juice may help relieve muscle cramps quickly, it isn’t because you’re dehydrated or low on sodium. It is more likely because the pickle juice sets off a reaction in your nervous system that stops the cramp, according to recent research."
