Run The Jewels' Killer Mike reportedly injured himself while putting grown man hands on a seemingly deranged fan who attacked the duo during a performance at SXSW, Monday (March 16). Following the wild incident Killa Kill flew back to his hometown, Atlanta, and visited a doctor who diagnosed him with a torn rotator cuff, he revealed to the crowd during a RTJ show on Friday (March 20) at Stubb's. The good doc also advised Mike to wear a sling. But apparently the rapper wasn't trying to hear that. "I was like, 'Doctor, I'm not leaving the road...The tour goes on!," he told fans in the venue.

Before rolling into "Banana Clip" at Stubb's - the song during which the man spazzed at the last show - Killer Mike let the rule be clear. "If you interrupt this song, we'll beat the fuck out of you," he said.

And that is indeed what happened at the last show, for reasons still unclear. No arrest were made and Austin Police said that the matter was handled by private security. Matt Sonzala, an independent promoter in Austin, told Buzzfeed that the man claimed Run the Jewels owed him money and stole his lyrics. He also said the man was later seen talking to himself.
