Junior dos Santos and Tim Boetsch show aftermath of UFC-155 losses

12,423 fans bought a record $3.2 million in tickets at the MGM Grand Garden to see the second meeting between Cain Velasquez and Junior dos Santos at the UFC-155 — and they got their money's worth.  But the heavyweight bout — which went a full five rounds — left dos Santos with a seriously beat-up face Saturday and might put him on the shelf for a while.

Velasquez — who waited over a year to reclaim his heavyweight title because of a shoulder injury — pounded his opponent pretty thoroughly and walked away with a unanimous decision.  

Later, dos Santos and Tim Boetsch — who lost to Costa Philippou after a stoppage in the third — showed off their bruised and cut faces in a photo from the hospital.

UFC president Dana white originally thought that dos Santos suffered a broken jaw in the title fight, but x-rays proved the fear was unfounded.

"I don't know if you saw [dos Santos] after the fight, but he looked terrible," White said.  "It's going to be a while until he starts training again."

It was dos Santo's first defeat since 2007 and he headed to the hospital right after the bout.

White said Velasquez is likely to fight again — probably against Alistair Overeem — while dos Santos heals.

To all you gamers out there who wince when you get blisters on your thumbs ask yourself one question after seeing this snapshot:  Do you still want to fight in the cage?
