Preliminary card picks

Although fights on the prelims don’t count toward the standings in the MMA Junkie staff picks, we still pick each fight. Here are some key results:

Of note, though it was set to open up the main card and not part of the prelims, Ismael Bonfim (19-4 MMA, 1-1 UFC) was a 10-1 pick from our staff members for his lightweight fight against Vinc Pichel (14-3 MMA, 7-3 UFC). Bonfim was a heavy favorite in the fight, but the bout was scrapped after he missed weight by 3.5 pounds.

Daniel Marcos (15-0 MMA, 2-0 UFC) was a 9-2 pick from our crew for his bantamweight fight against UFC newcomer Victor Hugo (24-4 MMA, 0-0 UFC), but Hugo missed weight by 2.5 pounds and that fight was scrapped, as well.

Our lone unanimous pick on the prelims is Rinat Fakhretdinov (22-2 MMA, 3-0 UFC), more than a 3-1 favorite for his welterweight fight against Elizeu Zaleski dos Santos (24-7 MMA, 10-3 UFC).
