Keith Richards says that he cracked a rib during the Rolling Stones tour this past summer.

Richards says that the incident took place at the Stones' July 4 show in Indianapolis.

He explained that he was running down the runway that extends out to the floor during the saxophone solo on "Miss You," and "somebody tossed a red straw boater hat," he recalled.

"It landed right in front of my feet. I kicked it aside - 'All right, that's out of the way' - and it f—ing bounced back in front of me, and I hit the floor.

And suddenly I'm on my hands and knees in front of 60,000 people. My bracelet came off from the shock. It was, 'Okay, get out of this one, pal!'"

"I might've cracked a rib," he added.

"There's nothing doctors can do about it.

I thought, 'S—, if I let them know how much I'm hurting, the doctors and the insurance companies will be like,

'Cancel the next gigs.' F— it. I'll live with it. After 50 years on the stage, you're going to fall over occasionally and take a knock."
