Le'Veon Bell is either insane or extremely confident ... the former star NFL running back will be fighting MMA star and former UFC fighter Uriah Hall in his pro boxing debut.
Bell will be fighting Hall on the same card as Jake Paul and Anderson Silva -- under "The Problem Child's" MVP promotion -- going down on October 29th in Arizona.
The fight will be fought at 195 lbs. ... and neither man can weigh over 200 lbs.
