Mayer is now in emergency surgery.
John Mayer is on the mend following an emergency appendectomy, his representative confirms to CNN.
Last night the "Your Body Is a Wonderland" singer was rushed to the hospital for an emergency appendectomy in New Orleans where he was set to perform on Tuesday evening.
Dead & Company tweeted that all tickets for the December 5 concert will be honored at the rescheduled date. Information on the rescheduled date will be announced as soon as possible. He postponed a Tuesday concert with Dead & Company at Smoothie King Center in New Orleans.
In the case that the fans will not be able to attend the show at another time, they will receive a full refund at the point of purchase.
Mayer plays lead guitar in the group that includes three original members of the legendary Grateful Dead.
This is a developing story.
Bob Weir tweeted a photo with his bandmate, captioning it, "Wishing a speedy recovery for John".
