Close your eyes.

Picture Jose Aldo beating the tar out of Mike Brown to initially win the WEC featherweight title. Then picture him hammering away at Urijah Faber's legs for five rounds. Finish it off by visualizing his massacre of challenger Manny Gamburyan at WEC 52.

Scary, huh?

What's even more terrifying is the recently revealed fact that "Scarface" did it all with a bum shoulder.

The UFC featherweight champ casually mentioned the previous injuries when explaining the reason he pulled out of his original title defense against Josh Grispi, which was scheduled for Jan. 1, 2011, to reporters during the UFC 129 conference call today.

Here's his story:

"There are two things that were bothering me. The first was on my neck, C5 and C6 [vertebrae], there was some pain on the disk. The main injury was my right shoulder which I think I injured during the Mike Brown fight. After that I still fought Urijah Faber and Manny Gamburyan. In both those fights, I felt my shoulder, especially fighting a wrestler like Faber, defending the takedowns, it put a lot of wear on my shoulder. I felt I just needed some time off to get back to 100 percent. I just needed rehab, not surgery."

Well rested. Hungry. And now healthy.

It's perhaps bad news for his opponent at the Rogers Centre in Toronto, Ontario, Canada, Mark Hominick. Then again, "The Machine" is on a five-fight tear, finishing four of those opponents.

He's been busy. Hungry. And also healthy. 

Care to take a guess which combination will emerge victorious on fight night?
