Two-time Olympic super heavyweight gold medalist Bakhodir Jalolov was set to snap a 15-month boxing hiatus on Thursday, though now will return to his California residence frustrated after the local commission refused him permission to box.

The giant Uzbekistan boxer, who has switched between amateur and professional codes in recent years, was scheduled to meet David Spilmont (16-8-1, 11 KOs) at the Montreal Casino, Montreal and weighed in at 254-pounds midweek.

News filtered through overnight via Top Rank's social media channels that Jalolov had fallen ill after the weigh-in, though the man himself provided an update translated to English by Uzbek news outlet Zamin.

“The fight has been canceled due to a minor incident. Both my opponent and I wanted to fight. Unfortunately, the commission did not allow it. I have had this condition since childhood. It happens when I fly to a country or change air," he stated in a brief video message.

Prior during the build-up to this co-feature bout of a show headlined by Movladdin Biyarslanov vs. Mohamed Mimoune at junior-welterweight, the 30-year-old spoke of his readiness for big showdowns in the paid ranks.

"This is a very big chance back to [go back to the pros} pros, now I have finished [in the] amateurs, now I am focused only on pros, now I am ready for any top fights," Jalolov (14-0, 14 knockouts) told The Ring through one of his team members.

"I'm always respectful of all the opponents, I am ready for this bout, and everything will show in the ring."

The working plan was for Jalolov to face Spilmont, and if victorious as expected, to stay busy before moving quickly into something more meaningful later this year.

"I am ready, waiting for big bouts," he proclaimed. "My goal is to go for big fights only with the champion now - no other options."

To that end, he would have to face Ring/WBA/WBC and WBO titleholder Oleksandr Usyk, with whom he shared a playful moment with, in Saudi Arabia.

"If they gave me two or three months, I would be ready for Usyk, it was friendly," said the 6-foot-7 southpaw of their meeting. "It is very interesting for me to compare my power with Usyk and [former heavyweight champion Anthony] Joshua because they are also Olympic champions. They reached good achievements as professionals."

While Jalolov is a national hero back in Uzbekistan, he is largely unknown in North America, that will likely change in the coming months, as he makes his way up the heavyweight ranks.

He was quick to send a short message to the top heavyweights in the world.

"I am coming, wait guys, I am coming...be careful," he said laughing.

The show will continue as planned with five undercard bouts preceding Biyaslanov-Mimoune, broadcast on ESPN+ at 6:30 ET/3:30 PT and in Canada on punchinggrace.com.
