Logan Paul Sparring With Gronkowski Bros To Prepare For Mayweather

Logan Paul has been training for his bout against Floyd Mayweather by sparring with a bunch of Gronks.

No, not Rob Gronkowski, the Tampa Bay Buccaneers tight end. Instead, Paul exchanges jabs with Gronkowski's four brothers -- Glenn, Dan, Chris and Gordie -- as relayed by TMZ Sports.

Yeah, there are five Gronkowski boys, and they all clearly possess enough fire to step into the ring for a throwdown. Well, except Rob, who has that whole football career to consider.

"I was the official referee, and good thing I was the official referee," Rob told TMZ. "My referring skills were pretty legit, 12 out of 10!"

Meanwhile, Paul praised the Gronkowski brothers based on girth alone.

"They're massive," Paul told TMZ. "I'm f**king 6-foot-2, 200 pounds and I go in there, and all of Rob's brothers are towering over me! They're all taller than me vertically, they're all wider than me horizontally. These are huge humans.

"Honestly, I walked in and I was like. 'Alright, I'm pretty sure I'm gonna kick their ass, but I cannot get hit obviously.' They don't know how to box, but they got some power and if they hit me, that could be it, man!"

Paul and Mayweather are scheduled to fight June 6 at Hard Rock Stadium in Miami. No word on whether the five Gronkowski brothers will attend.
