In late June and July, Vikings players scattered across the continent to train on their own in anticipation for training camp and the season.

Trae Waynes might have picked the most interesting place to work out.

Waynes and good friend and high school teammate Melvin Gordon spent Fourth of July weekend in Las Vegas, where they got a chance to train in the gym of undefeated world championship boxer Floyd Mayweather Jr.

While Mayweather was not present, Waynes said it was a thrill to lift weights, run on the treadmill, wallop a punching bag and do other exercises in the personal gym of one of the greatest boxers of all time.

"That's something you see on TV," the rookie corner said. "Actually being there was a cool experience because not a lot of people can do that."

Waynes has never met Mayweather. "I met his bodyguard, though." He said he was able to use his connections to get hooked up at the gym.

"Fortunately he was nice enough to open his gym for us," Waynes said, adding, "I would love to meet Floyd. I don't think there's a fight he's been in that I [rooted] against him. He's a great fighter, a great athlete."
