Gennady Golovkin and his trainer, Abel Sanchez, took shots at Canelo Alvarez’s performance-enhancing drug ordeal in a Jordan Brand commercial released Tuesday.

The camera then pans to Golovkin training in a boxing gym, where he hits a heavy bag, wraps his hands, skips rope and hits mitts with Sanchez.  When the camera returns to Sanchez, he ends the spot by stating, “And it’s called hard work.”

Using a steak as a prop and Sanchez’s statements are direct criticism of Alvarez testing positive twice in February for clenbuterol, a banned substance. Alvarez claims clenbuterol entered his system from contaminated meat he ate in his native Mexico, where meat contamination is a common problem.

Golovkin has repeatedly stated he doesn’t believe Alvarez’s excuse for failing those two PED tests administered by the Voluntary Anti-Doping Association.

The commercial concludes with the words, “No draw,” splashed across the screen in bold, white letters. The middleweight championship bout between Kazakhstan’s Golovkin (37-0-1, 33 KOs) and Mexico’s Alvarez (49-1-2, 34 KOs) resulted in a controversial 12-round draw September 16 at T-Mobile Arena in Las Vegas.

Golovkin, who has an endorsement deal with Nike’s Jordan Brand, sent out a link to the commercial through his Twitter account Tuesday morning (https://twitter.com/GGGBoxing). Several hours later, it had been viewed nearly 200,000 times.

The release of Golovkin’s commercial came a day before Alvarez’s hearing Wednesday with the Nevada State Athletic Commission. The NSAC is expected to extend Alvarez’s temporary suspension for his PED test failures at its monthly meeting in Las Vegas.

The 27-year-old Alvarez withdrew from their lucrative pay-per-view rematch April 3. It was supposed to take place May 5 at T-Mobile Arena, but it could be rescheduled for as soon as September 15, depending on the length of Alvarez’s suspension.

Golovkin still wants to fight May 5, but a potential fight against junior middleweight contender Vanes Martirosyan at StubHub Center in Carson, California, hadn’t been announced as of Tuesday afternoon. Golovkin doesn’t want to fight Ukraine’s Sergiy Derevyanchenko (12-0, 10 KOs), the mandatory challenger for his IBF middleweight title, on May 5, which has caused a delay in finalizing a fight against Martirosyan (36-3-1, 21 KOs).
