John Mayer has announced that more members of his touring band have tested positive for COVID-19, including the frontman himself. As such, he has rescheduled four upcoming dates for his Sob Rock Tour in Pittsburgh, Belmont Park, N.Y. and Boston.

Earlier this week, Mayer shared that drummer Steve Ferrone and Carlos Ricketts tested positive for COVID-19 and played special shows in New York and Washing D.C. with Questlove and J.J. Johnson, respectively.

The rescheduled dates have already been shared: tonight’s show at PPG Paints Arena in Pittsburgh will take place on May 5, the Belmont Park show has been moved from March 1 to May 7, and the two night run at Boston’s TD Garden set for March 5 and 6 will now take place on May 9 and 10.

“Whelp. More members of the band tested positive for Covid today, and I was one of them. This means we have to reschedule the next four shows, which we’ve already rescheduled and posted above. I’m so sorry to make you change your plans,” Mayer wrote in a statement. “This is a bummer for everyone in the band and crew, to say nothing of the question hanging over everyone’s head – mine included – as to how I tested positive on PCR twice in two months. (The first was extremely mild, but this one’s got the better of me.)”

Earlier this year, Mayer’s first experience with COVID-19 saw the guitarist pull out of Dead & Company’s destination festival Playing in the Sand. Read more.

The Sob Rock Tour will resume at the MGM Grand Garden Arena in Las Vegas on March 11.
