There is now opposition to the joint request, filed by Floyd Mayweather Jr. and Conor McGregor, to wear lighter 8-ounce boxing gloves in their megafight on Aug. 26 at the T-Mobile Arena in Las Vegas.

The Nevada State Athletic Commission confirmed last week that both fighters have made official requests to wear the lighter gloves for their 154-pound fight. According to state regulations, fights at over 147 pounds are required to use 10-ounce gloves.

"Both camps have submitted a waiver by the date we requested, which was [Wednesday]," NSAC executive director Bob Bennett told ESPN. "The commission will hear both camps' reasoning as to why it should deviate from its regulations during a scheduled meeting on Aug. 16." A decision will be made that day, Bennett added.

Mayweather first broached the topic on social media, saying he wanted the 8-ounce gloves. McGregor, a UFC champion stepping into the boxing ring for the bout, is used to mixed martial arts' 4-ounce gloves.

The state commission says the fighters' health and safety is the biggest factor in considering the smaller gloves.

Ahead of tomorrow's meeting,  the Association of Ringside Physicians sent a letter to the NSAC, to voice their concern over the use of 8-ounce gloves.

"The Association of Ringside Physicians understands that consideration is being given to amend current regulations, and in so doing, permit the use of 8oz Gloves in the forthcoming boxing match between Floyd Mayweather and Conor McGregor. This is a bout that has already been set a (sic) specific weight class. Unless there is scientific evidence to support the view that such a change might improve the safety of this bout, we would strongly caution against allowing current regulation to be over-ruled. To do so would also set a precedent for future bouts," wrote Dr. Raymond M. Monsell, who is the Chairman of the Board of Directors of the Association of Ringside Physicians.
