The UFC is rethinking its May 1 date in Montreal.
The calendar review is apparently due to rumblings that star boxer Floyd Mayweather may meet Shane Mosley the same day in Las Vegas.
UFC president Dana White confirmed via text Monday that the mixed martial arts organization is rethinking May 1 for UFC 113.
UFC light-heavyweight champion Lyoto Machida, due to meet Mauricio (Shogun) Rua in the Montreal main event, also signalled a possible change.
"My next fight against Shogun is scheduled for May 1, but there is a possibility to change," light-heavyweight champion Lyoto Machida said via Twitter. "If it does I'll let you know through here."
The all-Brazilian main event is a rematch of the UFC 104 bout in October when Machida won a controversial decision.
The scenario of Mayweather fighting on May 1 was fuelled by news that boxer Andre Berto, citing the disaster in Haiti where he has family, has withdrawn from his Jan. 30 welterweight title bout in Las Vegas with Mosley.
News of the possible change surfaced as news of more fights for Montreal came out.
Welterweight Josh Koscheck confirmed that he will meet England's Paul (Semtex) Daley on May 1 in the co-main event.
"This kid is going 2 get what he's asking 4," Koscheck said via Twitter.
And lightweight Dale Hartt tweeted that he has signed to fight Jonathan (The Road Warrior) Goulet at UFC 113.
