A five-round middleweight clash pitting Mark Munoz against Chris Weidman has been tapped as the main event of UFC on FUEL 4.

The summer event is slated for July 11, 2012, though a location and venue have yet to be confirmed. Ariel Helwani broke the news on Tuesday night's episode of UFC Tonight.

Munoz (12-2) rides into the bout sporting a four-fight winning streak, including a trio of victories last year over the likes of C.B. Dollaway, Demian Maia and Chris Leben that pushed his name into title contention. Munoz was previously booked to fight Chael Sonnen in a No. 1 contenders bout at UFC on FOX 2, however the 34-year-old abruptly withdrew from the event less than two weeks out due to an influx of bone spurs in his elbow.

Munoz's exit paved the way for Weidman (8-0) to enter as a late replacement at UFC on FOX 2, where he ultimately earned the biggest win of his career by out-pointing Maia for a unanimous judges' nod. The former two-time All-American trains under the guidance of former UFC champion Matt Serra and is 4-0 thus far in his brief UFC career, counting dominant victories over Alessio Sakara, Jesse Bongfeldt and Tom Lawlor.
