On this week's edition of "MMA Live" on ESPN 2, which as of this article has yet to air in the U.S., but has aired already in the the U.K., UFC president Dana White revealed the next number one contender for the heavyweight title. White noted that whoever wins the Junior Dos Santos vs. Roy Nelson fight at UFC 117 next Saturday night will challenge either Brock Lesnar or Cain Velasquez, depending on who leaves UFC 121 in October with the gold.
