Ben Simmons Puts Karl Anthony-Towns In Chokehold In Epic NBA Fight, He Tapped!

An NBA game turned into an MMA match Wednesday ... 'cause during a bench-clearing brawl, Ben Simmons put Karl-Anthony Towns in a chokehold -- AND KAT TAPPED!!!

The insane scene all went down in the third quarter of the Sixers-Timberwolves game ... when Anthony Towns got pissed over Joel Embiid's aggressive defense.

The two big men pushed and shoved ... and ultimately, EVERYBODY jumped into the fracas!!

At one point -- after Embiid and KAT were separated -- Simmons ended up on the ground on top of Anthony Towns ... and 76ers star began choking KAT out!!!

Karl quickly tapped ... and Simmons let go -- and the whole altercation was crazy/hilarious.

Maybe the best part of the entire skirmish? After Embiid was ejected ... he played it up to the crowd -- AND ANTHONY TOWNS' MOM BEGAN FLIPPING HIM OFF!!!

Cooler heads ultimately prevailed on the court -- the Sixers ended up winning, 117-95 -- but the battle continued to rage on on social media afterward.

"Great team win!!!" Embiid said. "I was raised around lions and a cat pulled on me tonight lmao @jimmybutler I missed being part of the 3rd stringers... I got his mom giving middle fingers. That’s some SERIOUS REAL ESTATE #FightNight #IAintNoBitch"

Didn't take long for KAT to fire back ... "I aIN’t nO BiTcH RaiSeD ARoUnD LiOnS #BitchTalk." He also tagged the location as, "All Bark & No Bite"

Amazing.
