The Jermall Charlo vs. Maciej Sulecki event, scheduled to take place Saturday, June 18 live on SHOWTIME from Toyota Center in Houston, has been postponed after Charlo suffered a back injury in training.

The card will be rescheduled to a new date that will be announced pending an assessment of when Charlo can return to training.

Also scheduled for the card was undefeated top super bantamweight contender Ra’eese Aleem taking on Mike Plania in the 10-round co-main event, and Derrick James-trained unbeaten lightweight contender Frank Martin was going to face Ricardo Núñez in the 10-round telecast opener. 

Charlo (32-0, 22 KOs) has been out of the ring since June of 2021, when he picked up a tougher than expected decision win over Juan Macias Montiel.

Sulecki (30-2, 11 KOs) was training for the fight in Chicago, Ill. with his new co-trainer and longtime Polish contender Andrzej Fonfara. He was looking to earn his third straight victory. The 32-year-old has never been stopped and won four of his last five fights. His two defeats came at the hands of Demetrius Andrade and Daniel Jacobs.
