Could you imagine what might happen if Jorge Masvidal and K amaru Usman ran into each other without any security nearby before their UFC 251 clash Saturday? Well, it almost   happened earlier this week while the two men were at the fighter hotel in Las Vegas prior to their departures for Abu Dhabi. As Episode 1 of the UFC’s “Embedded” series showed, they came this close to running into each other by the elevators when Masvidal was walking into one just as Usman was walking out of the other. It appeared, from the video, that Usman looked over and recognized the man walking into the elevator was Masvidal, but Masvidal was oblivious as he was occupied on his phone. “I didn’t know about it until they showed me the video, and that was pretty (expletive) trippy, man,” Masvidal said on “SportsCenter” on Tuesday night.
