The Brown Sugar guitarist delayed the A Bigger Bang tour by two months after he fell out of a tree while on holiday in Fiji in April and suffered head injuries.
But the 62 year old insists fans will see him at his best when the tour resumes in Italy later this month.
In a recording on his website, Richards says, "Hey, everything’s cool, my guitar is tuned, I’m ready to go. It was a nasty knock but we got over it and I’m ready to rock."
