Jake Paul is fresh off beating Anderson Silva ... but could he actually help his brother, Logan, come away with the Undisputed WWE Universal Championship, too?!?!
It certainly looks like a possibility ... with the Problem Child touching down in Saudi Arabia for the Maverick's huge Crown Jewel match against Roman Reigns!
It's a huge moment for Logan -- it's just his third WWE fight ever ... and he's going up against one of the greatest wrestlers in the promotion's history, who's currently the longest-reigning Universal Champion ever.
