LAS VEGAS (AP) — Nevada could start using instant replay in boxing and mixed martial arts within a month to help referees review crucial or controversial moments of fights.

The Nevada Athletic Commission approved limited use of the technology to help referees rule whether hits like low blows or head-butts are accidental — if they cause a fight to end because of injury.

Commission Executive Director Keith Kizer said Thursday that instant replay would be used at the sole discretion of referees.

Kizer says the new rule could be in effect within 30 days. It awaits approval from the state’s Legislative Council Bureau.

That means it’s possible that instant replay could be used during the Floyd Mayweather Jr.-Juan Manuel Marquez fight Sept. 19 in Las Vegas.
