The former NCAA Division-1 wrestler was awarded the ranking by Leandro Vieira of Checkmat BJJ a few weeks before his trilogy fight against Junior dos Santos at UFC 166, which goes down at Toyota Center in Houston, Texas on Oct 19, 2013.
See a video of his ceremony here.
Dos Santos originally dethroned Cain from the top of the 265-mountain in 2011 via first-round knockout. Two years later, Velasquez reclaimed the title by beating "Cigano" from pillar to post at UFC 155 in one of the most lopsided five-round title fights in UFC history.
Perhaps what was most impressive, was the fact that Cain dominated the fight on the feet, Junior's specialty.
The two will (possibly) conclude their rivalry at in "H-Town" in the main event of the stacked pay-per-view (PPV) card, which also features a co-main event fight pitting Daniel Cormier and Roy Nelson against one another and Gilbert Melendez taking on Diego Sanchez in lightweight action.
For the record, of his 12 mixed martial arts (MMA) victories, Velasquez has yet to record a submission win.
Can "Brown Pride" make Junior -- another jiu-jitsu blackbelt -- his first?
