The junior-welterweight contest between Adam Azim and Eliot Chavez has been cancelled by the British Boxing Board of Control.
England's Azim and Chavez, of Mexico, were scheduled to fight on the undercard of Saturday's European super-middleweight title fight between Azim's compatriot Callum Simpson and the Italian Ivan Zucco at Oakwell Football Ground in Barnsley, England.
The 30-year-old Chavez, however, according to a statement released on social media by the promoters Boxxer, no longer has the permission of the governing body of British boxing to fight, as a consequence of his using a sauna to make weight.
"The British Boxing Board of Control has withdrawn permission for Eliot Chavez to face Adam Azim in Barnsley following concerns raised by The Mexican Boxing Commission relating to Chavez's use of a sauna to make weight – a practice that is prohibited by the board," the statement read.
Azim, 23, had made weight on Friday. He would have been fighting for the first time since impressively stopping Kazakhstan's Sergey Lipinets in February. He and Chavez were scheduled to fight over eight rounds; their date had been confirmed only three days ahead of fight night.
"I'm incredibly disappointed that I am now not fighting," Azim posted on social media. "I was physically and mentally ready to put on a great performance. I'm not going to say anymore on this. Can't wait to box again soon. Allah is the best of planners."
