Now that he has signed a contract to fight Daniel Jacobs, Julio Cesar Chavez Jr. cannot miss a test by the Voluntary Anti-Doping Association.

VADA reported Chavez to the Nevada State Athletic Commission when its tester couldn’t locate Chavez last month. According to Hearn, Chavez had not yet signed a contract to box Jacobs when he wasn’t available for that VADA test, but that didn’t stop the NSAC from suspending Chavez.

Nevertheless, the Arizona Boxing & MMA Commission is expected to license Chavez to battle Jacobs on December 20 at Talking Stick Resort Arena in Phoenix. Their fight originally was supposed to take place at MGM Grand Garden Arena in Las Vegas, which was why the NSAC suspended Chavez.

When asked about Chavez missing a VADA test last month, Hearn told on Friday, “Yeah, because he hadn’t signed up for any contracts for any testing. And these people turned up at his door to test him. So, he said, ‘I’m not doing it.’ He’s fully signed up to all drug-testing agencies for this fight with the [Arizona] commission. So, you’ll find out. Do you know what I mean? Like, if he skips a test, he’s out of the fight because he signed for the fight. He hadn’t signed for the fight then. And this guy’s extremely paranoid, by the way, because his career has been tainted by his own problems.”

The 33-year-old Chavez (51-3-1, 33 KOs, 1 NC) has boxed only once since Mexican rival Canelo Alvarez dominated him in their 12-round super middleweight match 2½ years ago at T-Mobile Arena in Las Vegas. The son of Mexico’s most beloved boxer won that bout by first-round knockout against Colombian veteran Evert Bravo (25-11-1, 19 KOs) on August 10 in San Juan de los Lagos, Mexico.

Brooklyn’s Jacobs (35-3, 29 KOs) has moved up from middleweight to super middleweight for this fight. In Jacobs’ last outing, Alvarez beat him by unanimous decision in their 12-round, middleweight championship unification match May 4 at T-Mobile Arena.

Hearn – whose company, Matchroom Boxing USA, promotes Jacobs – expects Chavez to remain in their fight, despite the former WBC middleweight champion’s unpredictable nature.

“Gabriel Rosado is on the undercard, and he’s standing by to fight either man if someone pulls out,” Hearn said. “And one of the Mexican journalists says, ‘Well, that’s a bit disrespectful to Chavez.’ No, I said, ‘Chavez, he’s up and down. He can be unreliable. He’s in a great place right now. He’s training very hard. You saw him today. He’s in good shape. If he would’ve turned up heavy and then you have a problem.’ He’s in good shape. You see on Instagram – he’s in good shape. Unquestionably, he’s in good shape.”

DAZN will stream Jacobs-Chavez in the United States. Sky Sports is set to televise their 12-round, 168-pound bout in the United Kingdom.
