The Grammy-winning singer, songwriter and guitarist underwent surgery on Tuesday. A publicist for the 40-year-old said in a statement Wednesday that Mayer is recovering and "is in good spirits."
He had been touring with the Dead & Company.
The group postponed a New Orleans concert date on Tuesday and is now postponing two more dates in Orlando on Thursday and Sunrise, Fla. on Friday. Fans can use the tickets for the rescheduled date or get a refund.
