The Game Wants to Fight Jake and Logan Paul, I'll 'F***' You Up!

Another non-boxing star wants a crack at the Paul Bros -- The Game is calling 'em both out and GUARANTEEING victory!!

"Yerrr, @JakePaul, @LoganPaul .... meet me & my little brother downtown LA in front of Staples Center and let’s just fight head up fades," the rap superstar tweeted out.

"No gloves, no money needed ... just on some me & my brother will f*** you & your brother up s***!!!!"

FYI, The Game is 41 years old and has no pro boxing experience -- but he's been in a ton of street fights over the years and seems incredibly confident in his hands.

Someone on Twitter warned The Game about the call out -- "you and your brother game are gonna be like Nate Robinson don’t do this bro."

Game replied, "On Martin Luther King Jr. speech, I ain’t losing!!!"

Jake Paul -- who famously and violently knocked out ex-NBA star Nate Robinson and UFC fighter Ben Askren -- responded to Game, using a rap lyric.

"Hate it or love it you would get knocked the f**ked out."

Logan Paul -- who just beat up the entire Gronkowski family -- also weighed in ... telling Game, "you gonna need your entire family."

Logan is currently training to fight Floyd Mayweather -- but Jake is looking for his next opponent.
