Local boxer’s loss gets overturned by commission

The California State Athletic Commission overturned a pro boxing loss suffered by Luis Villagomez of Aleman Boxing Fresno, instead declaring his May bout with San Francisco’s Denis Madriz to be a no-contest.

Madriz was awarded a TKO when Villagomez was cut and the ringside doctor stopped the fight with 2 seconds left in the third round. The referee had ruled the cut was caused by a legal punch, but replays reviewed by the commission showed Madriz delivered an unintentional headbutt.

Villagomez is to box Tuesday at Table Mountain Casino on the undercard of the Christy Martin/Mia St. John main event.
