The Quebec Athletic Commission is looking at possible rule changes that could push the UFC away from running UFC 97 in Montreal, according to Sportsnet.ca.
UFC 97, co-headlined by Anderson Silva vs. Thales Leites and Chuck Liddell vs. Mauricio "Shogun" Rua, is currently scheduled for the Bell Centre in Montreal on April 18. Tickets have already went on sale.
According to Sportsnet.ca, possible changes include a smaller Octagon and prohibiting elbow and knee strikes.
It's almost a certainty that the UFC would not agree to these changes.
The Quebec Athletic Commission currently follows the Unified Rules of MMA and had no problem when the UFC debuted in Canada at the same venue last April. UFC 83 saw Georges St-Pierre reclaim his welterweight title in a dominant fashion against Matt Serra.
