Tevin Farmer couldn’t help but laugh when he was informed Friday that Joseph Diaz Jr. lost the IBF junior lightweight title at the scale.

Farmer feels Diaz being stripped of his 130-pound championship the day before what was supposed to be his first title defense is “karma” for Diaz not fighting Farmer again. Diaz defeated Philadelphia’s Farmer by unanimous decision to win that IBF belt a year ago, but Farmer didn’t get the immediate rematch he thought he was guaranteed in his contract because the deadline expired before it could be scheduled.

Diaz instead moved forward with a 12-round fight against Shavkatdzhon Rakhimov, the IBF’s mandatory challenger. Rakhimov made weight Friday (129.8 pounds), but Diaz stepped on the California State Athletic Commission’s scale at 133.6 pounds, roughly 3½ pounds above the junior lightweight limit.

The 28-year-old Diaz was subsequently stripped of his title. Tajikistan’s Rakhimov (15-0, 12 KOs) still can win the IBF junior lightweight crown by beating Diaz, but Diaz (31-1, 15 KOs) can’t retain it even if he defeats Rakhimov in a main event DAZN will stream Saturday night from Fantasy Springs Resort Casino in Indio, California (8 p.m. EST; 5 p.m. PST).

“I got a few phone calls about it and I was just like, ‘Wow!’ To me, he was never a world champion,” Farmer told krikya360.com. “As we all know in boxing, you’re not a true champion until you make your first defense. So, he got what he got. What goes around comes around. Karma’s a beast. That’s what he gets.”

Diaz’s disastrous trip to the scale surprised Farmer because the 2012 U.S. Olympian was in position to make at least substantial six-figure purses as a 130-pound champion.

krikya360.com has learned that the southpaw from Downey, California, was fined $100,000 from his $500,000 purse by the CSAC. Diaz paid half of that fine to Rakhimov and the additional $50,000 to the CSAC.

“It’s just shows a lack of discipline,” said Farmer, who lost to Diaz by scores of 116-112, 115-113 and 115-113 last January 30 in Miami. “I don’t even know what to think about it. It’s just stupid. He essentially was about to start making real money, and he loses his belt on the scale, like a dummy. I may have cut weight wrong in the past, but I always made sure I made weight.”

Whatever occurs Saturday night, Farmer (30-5-1, 6 KOs, 1 NC) isn’t interested in a rematch with Diaz anymore because he has been stripped of the title Farmer hopes to regain.

“Now,” Farmer said, “he can kiss my ass.”
