MANCHESTER, N.H. (AP) — Bret Michaels has ended a concert in New Hampshire after suffering a medical emergency.

Guitarist Pete Evick says on Michaels’ Facebook page the former Poison frontman was three songs into his set in Manchester on Thursday when he rushed from the stage.

A crew member says Michaels’ blood sugar was extremely low. The singer was diagnosed with diabetes as a child.

Evick says Michaels returned to the stage, telling fans he couldn’t continue performing. Evick says when he went to the band’s bus to check on Michaels, “he could barely speak, but begged me to apologize to the fans.”

On Twitter and Facebook, Michaels thanked paramedics who helped him.

In 2009, the rocker was performing at the Tony Awards when he was hit in the head with a set piece. He suffered injuries that he claimed contributed to a brain hemorrhage that nearly killed him.
