Al Iaquinta’s raging rants have been the story of MMA this week. Kevin Lee was the victim of some choice Twitter barbs from Iaquinta on Tuesday. So on Thursday, the Detroit native responded to his former UFC lightweight foe.

In an Instagram post, which featured a photo of Lee punching Iaquinta during their 2014 fight, Lee lobbed some trash talk right back at “Raging Al,” poking fun at his real-estate career and saying nobody wants to hear him complain about his UFC contract.

“Nobody give a fuck if u retire,” Lee wrote.

Iaquinta has been in a feud with the UFC in recent months, stemming from the promotion taking away his ability to make fight-night bonuses and an issue with the UFC paying for his knee surgery. Iaquinta considered retirement last year to focus on real estate, but came to knock out Diego Sanchez in 98 seconds Saturday night at UFC Fight Night 108 in Nashville.

Once again, Iaquinta was not given a $50,000 Performance of the Night bonus and that made “Raging Al” angry again. Iaquinta bashed the UFC on Monday’s episode of The MMA Hour, telling UFC president to “shut your f*cking mouth” regarding his comment about the flight home from UFC 208 being the best part of the night.

“Dana White has done a lot for this sport, but he’s not gotten one injury from this sport,” Iaquinta said. “And for him to say, ‘the best part of UFC Brooklyn was the flight home’ — you’re on a private jet, bro. Shut the f*ck up. You’re on a private jet. Most people, that would be the highlight of their life. Forget the night. You’re on a private jet, of course it’s the highlight of your night.”

Iaquinta went on a Twitter rant Tuesday, bringing Lee’s name into the fold, criticizing his ability to punch. The two have exchanged words on social media and in interview before. Iaquinta defeated Lee by unanimous decision in February 2014.

Lee, who fights Michael Chiesa in the main event of UFC Fight Night 112 on June 25 in Oklahoma City, obviously saw the tweets and Iaquinta’s comments about the UFC.

“Shut up and let the real men work stupid,” Lee wrote on Instagram. “Or keep f*cking things up for yourself. Nobody wanna hear a grown ass man complain, finish your bum contract and then we can talk again.”
