#3 Cain Valesquez
Cain Valesquez was embarrassed by Brock Lesnar the last time he stepped into a WWE ring before it was revealed that he needed knee surgery. That being said, the former MMA star is still expected to be part of the show after rumors suggested that he will be in the mix and could be the man who eliminates The Beast Incarnate.
The WWE Champion's match at WrestleMania hasn't yet been revealed, but it appears that if Valesquez is number two in The Rumble and is then the man who eliminates The Beast, then that would be enough to put him in position to challenge him at WrestleMania.
The match between the two men has been building for the past few months, but since Lesnar already defeated Valasquez in record time in Saudi Arabia, it would take something big to ensure that Lesnar would want to step back in the ring with someone who has already given him a lasting scar.
