Two of the hardest-working lightweights in the UFC will meet over Labor Day Weekend in the form of a clash between Danny Castillo and Michael Johnson at UFC 151. The September 1 scrap was confirmed earlier today by UFC officials.

Castillo has come out of the cage with his hand raised in three straight outings. The Team Alpha Male representative holds an overall record of 14-4 with nine stoppages as well as past wins against the likes of Joe Stevenson, Anthony Njokuani, and Dustin Poirier.

The 11-6 Johnson has also been hot as of late with back-to-back victories against Shane Roller and TUF winner Tony Ferguson.

UFC 151 is headlined by a title-fight featuring light heavyweight champ Jon Jones facing seasoned veteran Dan Henderson.
