SB Nation MMA's Luke Thomas (@MMANation) will be breaking down the two fights airing on Facebook for UFC on Versus 3: Sanchez vs. Kampmann, which is headlined by a Diego Sanchez vs. Martin Kampmann. The event will take place at the KFC Yum! Center in Louisville, Kentucky. In the co-main event, "The Ultimate Fighter" veteran C.B. Dollaway and NCAA Division I national champion Mark Munoz will look to move their careers past prospect status.

Two preliminary fights will air on Facebook beginning at 8 p.m. E.T. They are as follows:

On Facebook:
Joe Stevenson vs. Danny Castillo
Steve Cantwell vs. Cyrille Diabate

Neither fight carries much weight for their divisions, lightweight and light heavyweight. This also makes the first meeting for both pairs and the UFC debut of Castillo.

More on this later.
