The metal legends were due to perform at the State Farm Stadium in Glendale, Arizona on the latest stop on their M72 tour but have now moved the gig back to next Saturday as Hetfield has contracted the virus. "We're very sorry to report that tomorrow's scheduled M72 date at State Farm Stadium has been postponed to Saturday, September 9, 2023, as, unfortunately, Covid has caught up with James. We're extremely disappointed and regret any inconvenience this has caused you. We look forward to returning to complete the M72 No Repeat Weekend in Glendale next Saturday."
