Eric Clapton’s two shows at The Forum in Los Angeles this weekend will be rescheduled to September 13 and 18 after the guitarist came down with a case of severe bronchitis.

A statement on Clapton’s Facebook page notes that ticketholders can retain their tickets for the new dates or refunds will be issued at point of purchase. Clapton will also play the previously scheduled shows at The Forum on September 15 and 16.

“He is very sorry to disappoint his fans but looks forward to these shows,” the statement read. Clapton just wrapped up a run at Madison Square Garden where he was joined by Gary Clark Jr. and Jimmie Vaughan.
