Although most people have probably closed the book on UFC 158 and are looking forward to a bout between welterweight champ Georges St. Pierre and Johny Hendricks, Nick Diaz’s representatives apparently have unresolved issues with the champion and the Quebec athletic commission.

According to multiple reports, the Diaz camp is going to launch an official complaint with Quebec officials, regarding how the commission handled the UFC 158 weigh-ins and the supervision of post-fight drug tests.

Diaz’s representatives are arguing that the commission showed favoritism towards St. Pierre, by not accounting for decimal points in a fighter’s weight, like other jurisdictions do. Thus for example, if a fighter weighed in at 170.9 pounds, it was recorded as 170.

A video was posted recently at BJPenn.com, which showed a Quebec official explaining the rules to Diaz’s camp, prior to the weigh-ins. The news appeared to catch the group off guard. The official also relayed that Diaz and St. Pierre would be given an extra hour to cut weight if they missed the 170 mark.

In a follow up report from MMA Weekly, a commission representative reiterated that the rules do not account for a decimal point, however, Diaz’s camp insists that the bout was contracted for 170 pounds, not 170.9.

Several previous UFC events that have been held in Quebec utilized the same regulations regarding the weigh-ins.

As a result of the rules, the former Strikeforce champion’s representative Jonathan Tweedale stated that St. Pierre “remains legally and ethically obligated to fight Mr. Diaz at 170 pounds or else vacate the belt.”

In addition, Diaz’s camp is claiming that the Quebec Commission failed to “supervise fighters’ provision of samples in connection with testing for Prohibited Substances and Prohibited Methods.”

Prior to their March 16th bout, Diaz relayed at a press conference that he did not believe the Montreal fighter would be tested for performance enhancing drugs following the event.

Diaz lost by unanimous decision to St. Pierre at UFC 158, which was the outspoken fighter’s second consecutive defeat, after losing by UD to Carlos Condit last February.
