Former UFC heavyweight champion Brock Lesnar and former Strikeforce heavyweight champion and K1 Heavyweight Grand Prix champion Alistair Overeem are slated to face off against each other at the end of the year to determine the No. 1 contender to newly minted champion Junior Dos Santos.

Of course, mixed martial arts is different than kickboxing, but it isn’t as if Overeem is a fish out of water when the fight hits the mat or takes place in the clinch. He is a former Abu Dhabi Combat Club European champion, the prized organization for submission grapplers to compete. Not to mention the fact that 19 of his 35 wins come by way of submission, eight of which were his patented guillotine choke used to choke out Brazilian Jiu-Jitu black-belt Vitor Belfort.
