Mixed martial arts star Alex Pereira of Brazil has accused Frenchman Cyril Gane of landing multiple "illegal shots" during their fight for the interim UFC heavyweight title at the White House.

Gane finished off Pereira in the second round to win the title on Sunday after sending him stumbling with a right jab followed by a hammer fist.

The referee then stopped the fight 1:27 into the round after a left to the chin.
