Keith Richards of the Rolling Stones was discharged from a hospital in New Zealand on Thursday following surgery to relieve pressure in his head following a fall, his publicist said.

Fran Curtis said in a brief statement that Richards would remain an outpatient at The Ascot Hospital in Auckland and would return for checkups.

Richards suffered the injury on April 27 in Fiji. News reports have variously claimed that he fell out of a palm tree or from a jet ski. It was unclear how long Richards would remain an outpatient and Curtis could not immediately be reached for comment.

The Stones' "A Bigger Bang European" tour, which was scheduled to start in Barcelona, Spain, later this month, will be postponed until June, London-based publicists LD Communications said in a statement earlier this week.
