The drummer of Journey, Deen Castronovo, experienced an unspecified medical emergency during the band’s concert on Thursday night in Tulsa, Oklahoma.

Local sports reporter Eric Bailey shared a video from the show, indicating that Castronovo was assisted off the stage just two songs into the performance at the BOK Center.

“We’re going to see what happens as this progresses,” Jonathan Cain, keyboardist/guitarist, stated (as reported by Tulsa World). “It’s an unfortunate situation. We’re very sorry. We’re hoping it’s only a delay, but please — I’m sorry. Don’t worry. Have your prayers ready. Have your prayers ready for Deen Castronovo, everybody. Thank you.”

Shortly after, guitarist Neal Schon provided an update on Castronovo’s condition. “He’s heading to the hospital. We’re going to continue the concert, and Deen’s tech, his drum tech, is going to sit in with us tonight,” he explained in a video shared by The Hair Metal Guru. “Please give a big hand for (longtime Journey drum tech) Steve Toomey. We’ll be back in about 15 minutes. We love you all; we’re really sorry about the inconvenience.”

When the show resumed, singer Arnel Pineda shared an encouraging message. “We ask for your prayers for our brother Deen Castronovo. He’s gonna be fine. Too much Gatorade.”

Later in the evening, Schon echoed Pineda’s optimism: “This concert’s for Deen tonight. I’d love you all to pray for him. Everybody’s been going through a lot. I think he’s going to be fine.”

This is a developing story which will be updated as needed.
