The Little Person Jake Paul and Mike Tyson fight doom in the Vegas club

Jake Paul And Mike Tyson will face off next week at AT&T Stadium in Texas … but fans who can’t wait to see the two brawl have another chance – in the form of a pair of small, similar people.

The MicroMania Tour – a group that puts on hilarious fights between little people – is taking over the Nerd Bar… a Las Vegas hotspot off the Strip, on Fremont Street.

In what they call “Micro Square Garden,” two performers with fake tattoos face each other in the center ring.

It’s unclear how many people will want to participate… or whether Vegas betting odds will reflect the brawl winner.

Right now, the fight is swinging wildly Jake’s way… with the 27-year-old reportedly holding on to a betting line of -270 CBS Sports.

However, Tyson was the undisputed heavyweight champion from 1987 to 1990 and compiled a career record of 50-6… so fans shouldn’t discount Iron Mike just yet.

Meanwhile, Tyson made headlines their press conference in August …as Iron Mike shoved Paul – all while cackling at JP’s annoyed behavior.
