(They should have included a can of soda for size comparison.)

With Brock Lesnar vs. Alistair Overeem, the UFC will arguably be presenting the most dynamic wrestler vs. striker battle that the heavyweight division has ever seen — but if you really want to hook the casual fans, it’s a lot easier to say “gawd damn these sons-a-bitches are huuuuuge!”

Which they are, of course. This might be the first time that Lesnar will look out-sized in the cage. And after Brock’s year-long illness layoff, Alistair isn’t exactly the ideal return opponent. But hey, this is MMA, anything can happen, etc.

A superstar on the rise, fist-posing next to a possibly-retired legend who barely has the strength to shaka — you can put this photo in the MMA dictionary next to “changing of the guard.”

UFC 137 provided another example of the unique emotional arc that this sport sometimes gives us. Headliners Nick Diaz and BJ Penn got into a near-tussle at the weigh-ins, spent three rounds trying to knock each other out, and after the fight they were chillin’ like two old bros. Never mind the fact that Penn’s left eye was leaking blood from all the blows he ate from Diaz, who happened to break the record for significant strikes landed in a UFC fight, by the way.

After the jump: More UFC 137 post-fight press conference highlights, in which Diaz talks about why he didn’t want to fight Penn, and explains that he didn’t go to school for buying a house. (That’ll make a little more sense when you watch it.)

Demetrious “Mighty Mouse” Johnson and Pat Barry will spend all fight looking up nostrils when they take on tall-for-his-weight-class Dominick Cruz and tall-for-humanity Stefan Struve (respectively) this Saturday. Don’t forget to come back to CagePotato.com for round-by-round results from the Versus main card broadcast of UFC Live: Cruz vs. Johnson, starting at 9 p.m. ET. In case you’re curious, there’s a photo of Stefan Struve and Demetrious Johnson standing next to each other after the jump. Not for the faint of heart.

From Fedor Emelianenko to Dwayne Lewis, gruesome eye injuries are so hot right now in MMA. So we thought we’d make them the subject of our latest photo tribute. Because it’s all fun and games until…you know. Lots more after the jump.

Don’t ask us to explain it, but whenever fighters and fans get together for a group photo, at least one person has to raise their fist like a tough guy. But instead of dropping the ban-hammer on this bizarre phenomenon, we decided to compile the most ridiculous, hilarious, and straight-up awesome MMA fighter fist-pose photos that we could find. If we left out any of your favorites, please shoot us some links in the comments section…

Well, Anderson Silva is officially dead to Wanderlei Silva now.  Here he is training Rich Franklin, who will fight “The Axe Murderer” at UFC 99 in Germany, and also presumably whispering to him about where to find the secret Brazilian “off-switch” to put Wanderlei’s lights out.  Hint: it’s located somewhere in the chin region.  In the past Brazilians have often balked at the idea of training a foreigner to fight one of their countrymen, but Anderson is like Bruce Lee: he teaches whoever wants to learn.  Especially if that person is about to fight someone he’s not particularly fond of at the moment.
