Bon Jovi abruptly ended their sold out Madison Square Garden concert 90 minutes in Thursday night, as frontman Jon Bon Jovi has been dealing with a sinus infection.

The rocker indicated he was OK and would try to reschedule the show.

“Don’t throw away your ticket stubs I’m going to figure something out, OK? Don’t [fear],” Bon Jovi told the audience, according to People and fan videos from the show. “Just hang onto it, I’m going to figure out how to reschedule.”

“I’m gonna have to cool it for a night,” he added, before exiting the stage, People reported. “I feel great, I’ll see you again soon, bye bye.” He had previously brought out Train singer Pat Monahan to join him on “Livin’ on a Prayer,” which was the last song of the shortened show.

A rep for Bon Jovi said in a statement, “Jon Bon Jovi spoke from stage and told fans he has been battling a sinus infection which led to the show’s early ending. As part of the Bon Jovi residency at Madison Square Garden, Jon has said numerous times that it has been a joy to return to live shows for the band. Updated information will be available shortly.”
