Tonight's the night ... WWE Superstar Big E is cashin' in, using his coveted 'Money In The Bank' briefcase for a title shot against Bobby Lashley -- or Randy Orton on tonight's Raw.
TMZ Sports talked to E ... and the 35-year-old SmackDown star, holding the 'MITB' case, made the announcement.
"I'm a big proponent of setting your intentions, and I woke up this morning and I said, let me set my intentions to be a world champion here tonight in Boston," Big E tells us.
Of course, Big E won the 'Money in the Bank' ladder match in July ... entitling him to a title shot against either the Raw (Lashley) or SmackDown (Roman Reigns) champ at any moment.
Bobby is set to face Orton tonight ... so, E could wrestle either of the men.
Lashley's the current champ ... so we asked him if he had a message for the Raw champ.
"First and foremost, Bobby needs to worry about a certain 14x world champion in Randy Orton, who's trying to become a 15x champion tonight. so he's got that to worry about. so my message to bobby is worry about that apex predator first. Just know, I'm here. I'm in the building."
