Top Rank's CEO Bob Arum is shaking his head at the controversial situation involving former WBC middleweight champion Julio Cesar Chavez Jr.

On December 20, Chavez Jr. is scheduled to fight Daniel Jacobs in a main event bout on DAZN.

The fight was originally scheduled to take place in Las Vegas - but Chavez Jr. was suspended by the Nevada State Athletic Commission.

The NSAC suspended Chavez Jr. over his refusal to take a random drug test. They sent a VADA agent to the Wild Card Boxing Club in Los Angeles, where Chavez Jr. was training, and the boxer refused to submit himself to a test.

Chavez Jr. claims the NSAC had no jurisdiction to make him take a drug test.

According to the NSAC, they had jurisdiction to test the boxer once promoter Eddie Hearn had officially requested a date for the scheduled contest with Jacobs.

Once the NSAC suspended Chavez, then Hearn moved the entire event to Arizona.

The NSAC has warned Hearn, that proceeding with the fight, while Chavez remained is suspension, would place his promotional license at risk in the state of Nevada. It would also be a federal violation of the Muhammad Ali Act.

Chavez has filed a lawsuit against the NSAC, attempting to overturn the suspension. At the moment, the fight in Arizona is still proceeding, but there is no official word from the Arizona Commission on where they stand on the matter.

"[Hearn is] in a strong position in the UK where the fans really buy tickets, but he's falling on his ass in the United States, because he doesn't understand the market and says stupid things. And what he's doing now with Chavez, putting himself at risk with the Nevada Commission, is senseless," Arum told a group of reporters.

"Any promoter who tries to put on a fight with a fighter who is suspended by a commission in the United States - should have his license taken away and not be allowed to promote. If we don't respect the laws and we don't respect the Muhammad Ali Act - then we have nothing. I don't care where guy comes from.

"His excuse may be that he's out of the country. But he should know the rules. You don't take a fighter who is suspended by a commission, and then take him to another commission or anywhere else to get licensed. You just don't do that or otherwise you destroy the sport. Once a fight is announced, the Nevada Commission has jurisdiction to test a fighter. A lot of fighters take performance enhancing drugs and then clear their system by the press conference, so if you wait until the press conference you will miss that they took performance enhancing drugs.

"The NSAC sent a VADA agent to Chavez's camp at the Wild Card. The guy waited all day and Chavez refused to get tested - now that's grounds for suspension and that's what the Nevada Commission did. What Eddie Hearn is trying to do, by going around the Nevada Commission, and taking it to the Arizona Commission, which is a violation of federal law, trying get him licensed, is a [disgrace] and everyone who cares about boxing should step up and let their voice be heard.

"He doesn't understand the laws in the United States. He is totally in disregard. He is a guy who has operated under the British Boxing Board of Control, which is not a government agency. It's an organization set up by the promoters and they have different rules and standards unlike the ones in United States, which are government agencies. If you notice in Arizona, they have not licensed the fight or licensed Chavez. They are holding back because [Chavez] has another hearing, on December 18, two days before the fight. I don't think when push comes to shove, that Arizona will defy the Muhammad Ali Act.

"DAZN has not been successful in the United States. They have not gotten any traction to speak of, with all of the millions that they've spent on their boxing in the United States - except for one guy, and that is Canelo Alvarez. Canelo has done tremendous numbers. The people who run DAZN, above Eddie Hearn, they are not boxing people. And what does that tell them..... that Canelo gets all of the subscribers that DAZN has, so they have to go out and get Hispanics, prominent Hispanics that move the needle.

"And you know and I know, that Chavez has disgraced himself before, that that he fought Canelo and didn't throw a punch, that most people in boxing see him as a joke. You know that and I know that, but he speaks Spanish so let's get him for Daniel Jacobs."
