Referee faces fan backlash at UFC Rio
Before the co-main clash at UFC Rio, there was a welterweight clash between Joel Alvarez and Vicente Luque. The bout became controversial when Alvarez knocked down Luque with a left hook in Round 1.
Luque complained about an eye poke, but replays showed the blow was legal. Instead of awarding Alvarez a TKO victory, referee Osiris Maia called in the doctor and later restarted the fight, for which Maia received backlash.
Also, referee Marc Goddard was called out by several fans after Kaan Ofli secured a controversial Round 1 submission over Ricardo Ramos in the main card opener at UFC Rio. Fans accused Goddard of not stepping up despite Ofli grabbing the fence several times.
