Junior dos Santos vs Cain Velasquez set for UFC year-end event on Dec. 29 in Las Vegas

Sorry, Alistair Overeem.

UFC President Dana White announced at the UFC 150 post-fight press conference last night (Aug. 11) that Junior dos Santos will, in fact, defend his heavyweight championship at the upcoming annual New Year's Eve event scheduled for Dec. 29, 2012, in Las Vegas, Nevada.

And, as expected for months now, Cain Velasquez will be the man challenging for the title.

It's no surprise, really. Overeem's hopes of fighting on that date were always a pipe dream and it looks far more likely that he'll be the man awaiting the winner of Dos Santos vs. Velasquez sometime next year.

Following their first fight, the highly publicized UFC debut on FOX late last year, Dos Santos and Velasquez seemed to be on a collision course. They were slotted on the same card at UFC 146 with Frank Mir and Antonio Silva acting as obstacles.

Ultimately, they weren't much more than speed bumps who got ran over by the two best 265-pound fighters in the world.

Now, the promotion has a mega main event rematch for its year-end extravaganza in "Sin City" and a ready made number one contender waiting in the wings, hungry to prove himself after a long suspension. And that's without even mentioning Daniel Cormier, who could have disposed of Mir in Strikeforce by then and made his case for a shot at the strap.

The heavyweight division is alive and well, Maniacs.
