Abner Mares of Hawaiian Gardens was really looking forward to his challenge to featherweight world champion Jesus Cuellar of Argentina. They were to tangle June 25 at Barclays Center in Brooklyn on the undercard of the Keith Thurman-Shawn Porter welterweight title fight (on CBS).

However, the bout was canceled Friday because Mares has an unspecified medical condition that will prevent him from fighting in the state of New York. DiBella Entertainment is the promoter for the Premier Boxing Champions presentation and it sent out a statement informing the media of the situation, while also making sure we knew that this medical condition is not life-threatening, nor does it have anything to do with performance-enhancing drugs.

The main event between Thurman and Porter will go on as scheduled and the Mares-Cuellar TV spot will be taken by another fight.

Mares has won titles in three weight classes.
