How did these two get here?

Mark "The Filipino Wrecking Machine" Munoz came over from the WEC as a light heavyweight, but a knockout loss to Matt Hamill led to a drop to middleweight. He has flourished in the division thus far, going 7-1 and taking out names such as Chris Leben and Demian Maia. He'll face what is probably the toughest test of his career in Weidman with a possible title shot on the line.

Chris Weidman is a two-time NCAA Division 1 All-American in wrestling, and has shown great promise in his brief MMA career to date. In just his third pro fight, he knocked out Uriah Hall to win the Ring of Combat middleweight title. After another decision win later in the year, Weidman was brought into replace Rafael Natal and took on veteran Alessio Sakara at UFC on Versus 3, where won a 30-27 decision. He was again a late replacement at UFC 131, where he submitted Jesse Bongfeldt with a brutal standing guillotine at the end of the first round. He then took on tough veteran Tom Lawlor at UFC 139, and put him completely to sleep with a tight D'Arce choke.He then stepped up on late notice again to face Demian Maia at UFC on Fox 2, and picked up a decision. This is undoubtedly the biggest fight of his short career.

Why should you care?

This is an extremely important middleweight fight, and the fighters match up very well. It might not turn into the most exciting fight ever, but relevance alone should get you to tune in.
