Las Vegas (AFP) - Boxer-promoter Floyd Mayweather has been ordered to appear before Nevada boxing officials who want to question him about events in his gym that were aired recently on the Showtime sports network.

The Nevada Athletic Commission says it wants to ask Mayweather about how sparring sessions are conducted in his gym and another scene that included women apparently smoking marijuana inside the facility, the Las Vegas Review-Journal reported Friday.

Mayweather did not participate but was shown telling someone else to get some rolling papers for the ladies.

The scene aired on Showtime prior to his world title fight against Marcos Maidana last week.

Another scene showed marathon sparring sessions, including one that went on for over 30 minutes. In the clip, Hasim Rahman and Donovan Cameron are shown in a lengthy battle, while Mayweather's team appears to bet on the outcome, the newspaper said.

"The doghouse; the rules are you fight till whoever quits. Guys fight to the death. It is not right, but it is doghouse rules," Mayweather said on the Showtime episode.

Mayweather was given his Nevada promoter's license in July.

"My main concern is the health and safety of the fighters," commission chairman Francisco Aguilar told the newspaper.

"It is not just about fight night but about training and sparring.

"When you hold a promoter's license in Nevada, you are expected to conduct yourself properly and I think some of the commissioners have some concerns over what they saw."
