Former UFC middleweight champion Anderson Silva says he’s no longer part of the UFC 212 card in Rio de Janeiro.

Silva (34-8 MMA, 17-4 UFC) was originally scheduled to fight at the June 3 pay-per-view event, but he was left without an opponent after Kelvin Gastelum (13-2 MMA, 8-2 UFC) was pulled from the card due to a failed drug test.

Silva said during a live Instagram stream (via UOL) on Sunday that he was “disassembling” his camp and, without too much detail, announced he was vacating his spot on the home-country card. The video is no longer available for viewing.

“I really wanted to fight in Brazil, my country, but it’s not going to happen,” Silva said. “I want to apologize for this. I really wanted to fight here, but it didn’t happen. I think I was hurt in this, but that’s it.”

The UFC has yet to make any official announcements, and Silva remains listed on the official UFC 212 event page against a “to be determined” opponent. When contacted today by MMAjunkie, a UFC official said nothing is yet official.

The ex-champ even took part on the event’s official press conference, facing off against himself and poking fun at the situation (watch it above). The playfulness, however, ended during a recent spot on “The MMA Hour”, where Silva went on a tirade about his dissatisfaction with the UFC.

“I’m very disappointed,” Silva said at the occasion. “The guys don’t respect my legacy, don’t respect my story in the sport. I don’t know. I’m done.”

The MMA great threatened to retire if he wasn’t given an interim title fight against Yoel Romero. UFC President Dana White, however, was quick to call the ex-champ’s bluff, saying that if he was “considering retirement, he should probably do it.”

Gastelum, who tested positive for marijuana metabolites in an in-competition sample stemming from his UFC Fight Night 106 scrap with Vitor Belfort in March, was recently issued a three-month suspension by the Brazilian Superior Justice Court of MMA. He was also fined 20 percent of his fight purse and had his TKO win overturned to a no-contest.

The timing would allow Gastelum to compete on a desired UFC on FOX 25 scrap with Silva on July 22.
