Watch UFC Fight Night 78: 'Magny vs Gastelum' online and on FOX Sports 1

Ultimate Fighting Championship (UFC) heads to Mexico for the second time in 2015 when UFC Fight Night 78 packs the house inside Arena Monterrey in Monterrey later tonight (Sat., Nov. 21, 2015).

The evening's featured bout is an exchange between rising Welterweight contenders Neil Magny and Kelvin Gastelum. Meanwhile, ex-Featherweight title challenger Ricardo Lamas welcomes the always exciting Diego Sanchez to the 145-pound division in the co-main event.

But, before we can get to the evening's main courses, fight fans will be treated to a trio of "Prelims" tussles set to begin at 6:30 p.m. ET on Fight Pass, before four more broadcast at 8 p.m. ET on FOX Sports 1.

A Lightweight tilt between Brazilian prospects Valmir Lazaro and Michel Prazeres kicks off the action.
