Quebec explains UFC 158 weigh-in loophole | UFC NEWS
Ultimate Fighting Championship (UFC) Senior Vice President of Business and Legal Affairs and Assistant General Counsel Michael Mersh handled it peculiar fashion.
Just prior to approaching the scale, Diaz and his camp were made aware that both fighters were allowed to weigh in over the 170-pound weight limit — so long as they came in under 171.
That information came just a few minutes before weigh-ins and was caught on video tape
The information did Diaz little good and when asked why said information was not made available beforehand, Mersh indicated it was an “off the record type of thing.” It’s since been called the “Canadian Loophole.”
MMAmania.com contacted representatives from the Régie des alcools des courses et des jeux (Quebec’s athletic commission) confirmed that both fighters made weight within the parameters of their contracts. In addition, their regulation on combat sports does not take decimals into account.
Both St. Pierre and Diaz could have weighed anywhere from 170.1-170.9 and still qualified as 170. That is not the norm in the Unified Rules of Mixed Martial Arts (MMA), where championship bouts must be at the established weight limit.
