The UFC's annual Memorial Day card in Las Vegas will have two massive heavyweight fights on top. One will be for the UFC heavyweight title, and the other might decide the next challenger after that. UFC Tonight was the one that broke the news (via Ariel Helwani):
Cain Velasquez (11-1) regained his heavyweight title with a decision win over Junior Dos Santos (15-2) at UFC 155, while Antonio Silva (18-4) knocked out Alistair Overeem (36-12, 1 NC) in the third round in their UFC 156 encounter. So now Bigfoot will get a title shot, just one year after being dominated by Velasquez and finished in the first round at UFC 146. Overeem vs. Dos Santos had been scheduled for that same card, and will now take place in a probable number one contenders bout instead of for the title.
