Big Boi isn't able to live up to the name of his Shoes for Running tour after he experienced an unexpected injury earlier this week.

The OutKast member was performing in Illinois on Sunday night (May 26) when he hurt his leg. He shared the news and a photo of himself on crutches through his Tumblr page.

"Injured my leg on stage yesterday , headed to the A for some test #TooTurntUp #Turndownforwhat #weoutchea," he wrote.

As a result of the mishap, Sir Luscious Left Foot had to cancel a show in St. Louis. "Currently on his headlining Shoes For Running tour, rapper Big Boi of Outkast has injured his leg while performing yesterday forcing him to cancel his St. Louis show today," a rep for the rapper said in a statement issued to RapFix. "Currently going through testing, Big Boi apologizes to his St. Louis fans for canceling the show."
