Mac Miller collapsed on stage on Aug. 10 during a stop on his Space Migration tour.
The Pittsburg native fell on the stage floor while performing Watching Movies in Phoenix, shown in the video below around the 2:05 mark. Members of his band rushed to his aide. After the lights dimmed, the rapper got up and continued his performance.
There's no explanation as to what caused his collapse but judging from past tweets it seems the rapper was exhausted.
"In Vegas. Need sleep," he tweeted on Aug. 8.
Miller has been on the road since July, touring all over the U.S. Some stops included California, Arizona, Utah and Idaho. The Life Ain't Easy rapper was accompanied by Odd Future's Earl Sweatshirt, Chance The Rapper, a duo called The Internet and rapper Vince Staples.

The rapper explained his hopes for his Space Migration tour, during an interview with Philly.com in July.
"I think [that] like the whole idea of everything [on this tour] is [to] kind of bring people into it [from an] alternative world. I think it's kind of [like] the Space Migration [tour] is [a place] where we're migrating people into a different universe and [a] different place. We're kind of trying to take people of out reality," he said.
The 21-year-old will also head overseas in September to perform shows in the United Kingdom, France, Norway, Sweden and Australia.
