UFC 155: Junior dos Santos will submit someone someday ...

... but it probably won't be Cain Velasquez. That's not the plan, anyway.

Junior dos Santos will defend his heavyweight championship against the man he won it from, Velasquez, at the Ultimate Fighting Championship (UFC) year end extravaganza at UFC 155 on Sat., Dec. 29, 2012, in Las Vegas, Nevada.

And -- surprise! -- he's looking for the knockout. But he's also prepared for the takedown where we might finally see some of that vaunted Brazilian jiu-jitsu he possesses, as told to Tatame.com.

"What I can tell you is what I've been doing on my preparation. I guess he's trying to take me down anyway he can and, since I prefer to stand-up, I'll try to keep actions up and go for the knockout again. I'm very well prepared, training a lot of ground game too and who knows? If he takes me down maybe I can submit him. After all, I train Jiu-Jitsu a lot and, as a Brazilian, someday I'll submit someone."

These two first met late last year at UFC on Fox 1 on Nov. 11 in Anaheim, California, an event that drew an average of 5.7 million viewers with a peak of 8.8 million during the main event.

It probably would have been much more had the fight lasted longer than it did, a whopping 64 seconds. That's all the time it took for "Cigano" to land one of his Brazilian bombs, putting Velasquez down for the count. Now, after a dominant stoppage win over Antonio Silva at UFC 146 in May of this year, the Cain Train is coming back to claim the title that was his.

Assuming he can pry it from Dos Santos' hands.

Anyone think Velasquez will take the champion down this time? If he does, will we be surprised with Junior's jiu-jitsu? Or are we simply looking at another short knockout victory for "JDS?"
