In fairness, Vaseline and adhesive can look awfully similar once they're removed from their containers.
On April 12 at Watch Out Combat Show 24 in Rio de Janeiro, Carlos Alberto Lobo (2-0) returned to his corner after the second round of his fight. As officials worked to reaffix an advertising banner to a cage post above him, some of the adhesive dripped onto the fighter's eye. Lobo immediately rubbed it, assuming it was Vaseline, and the damage was done.
Extra light, fingers, gloves, gauze pads, scissors and brute force couldn't get the eye to fully reopen, so Lobo's bout with fellow featherweight Marcos Nene (0-1) was waved off.
A restless crowd then booed the final verdict. While initially declared a no-contest, Lobo had won the first two rounds on the judges' cards, so he ultimately was awarded the technical unanimous-decision win.
Check out the craziness above.
