WWE Superstar Brock Lesnar was spotted in the crowd at Saturday's UFC 146 PPV and was shown on camera before the Frank Mir vs Junior do Santos main event. UFC big wig Dana White was asked later in the show if a return to the Octagon was on the cards for the former Word Heavyweight Champion, to which he responded simply by saying "Yeah". This has led to much speculation as to whether or not Lesnar could return to UFC despite being locked in a one year deal with the WWE that doesn't expire until WrestleMania 29 in March 2013. Sources are questioning whether this is all part of the 'Brock Lesnar quits WWE' storyline or if he actually has intentions of stepping back inside the MMA cage environment. Is this Lesnar's way of putting Vince McMahon and co. on notice? Is Brock using WWE for a bit of extra cash ($5 million) while he recovers enough to make his MMA comeback? Or is this like when CM Punk showed up on a few indie shows with the WWE title belt after he 'quit' last year only to return a few weeks later? Currently everything is still very much speculation and What Culture will bring you any updates as and when they happen. But what we do know to date is that Lesnar hasn't been all that happy with how he has been utilisied in his return to the WWE and WWE officials half expect him to quit his limited contract at any time. What do you think about Lesnar appearing on a UFC PPV so soon after re-signing with WWE? Is this legit or is it a work? Have your say below.
