(NEW YORK) — The Rolling Stones is pushing back the next leg of its North American tour because frontman Mick Jagger needs medical treatment, according to a statement.

The tour was expected to kick off in Miami on April 20.

Jagger is expected to make a “complete recovery.” “I hate letting our fans down and I’m hugely disappointed to have to postpone the tour but am looking forward to getting back on stage as soon as I can,” the 75-year-old said in a statement.

Tour promoters advised ticketholders to hang on to their existing tickets because they will be valid for the rescheduled dates.

Shows postponed in the U.S. are Miami; Jacksonville; Houston; New Orleans; Glendale; Pasadena; Santa Clara, California; Seattle; Denver; Washington, D.C.; Philadelphia; Foxborough, Massachusetts; East Rutherford, New Jersey; and Chicago.
