Michaels was performing with his solo band at the Palace Theater and shortly into the band's set the singer was forced to rush off stage. Evick posted the news to fans on Michael's Facebook page. He wrote, "This is a message I never imagined I'd have to post. Tonight in Manchester, NH, three songs into the set Bret had me sing a song as he rushed off stage.

"In the nine years I've stood next to him, I've never seen a look like the one on his face as if I was a complete stranger. One of the crew returned instantly to notify me that Bret's blood sugar was extremely low.

"He returned to the stage only to announce that he could not continue. As you all know he is a health fanatic and fiercely monitors his blood sugar, he basically had to be dragged off the stage in his sickest of conditions. When I rushed to the bus he could barely speak, but begged me to apologize to the fans and seemed only concerned for them.

"As of now he is with paramedics being evaluated. We will keep you posted throughout the evening."
