Journey's farewell tour took a frightening turn Thursday night when drummer Deen Castronovo was rushed to a hospital after suffering a medical emergency just two songs into the band's concert at the BOK Center in Tulsa, Oklahoma, halting the show and leaving bandmates begging the crowd for prayers.

Castronovo, 62, was helped off the stage as his bandmates stopped playing, according to multiple accounts of the Thursday-night show. Keyboardist Jonathan Cain addressed the stunned arena first, calling it "an unfortunate situation" and telling fans the band hoped it would be only a brief delay. About ten minutes later, guitarist Neal Schon returned to the mic with an update: Castronovo was already on his way to the hospital.

Rather than cancel the show outright, Journey pressed on with Castronovo's longtime drum tech, Steve Toomey, sliding behind the kit for the remainder of the set, according to Billboard. Frontman Arnel Pineda tried to lighten the mood from the stage, telling the crowd Castronovo was "gonna be fine" and joking it was "too much Gatorade," per Ultimate Classic Rock.

The scare landed in the middle of Journey's "Final Frontier Tour," the band's long farewell run that kicked off February 28 in Hershey, Pennsylvania, and resumed its current leg September 12 in Los Angeles. Tulsa's News On 6 reported that first responders were stationed outside the BOK Center as the concert carried on, though no details of Castronovo's condition were released that night.

"This Concert Is For Deen"

Before launching back into the set, Schon dedicated the rest of the night to his bandmate.

"THIS CONCERT IS FOR DEEN. I THINK HE'S GOING TO BE FINE."

As of Friday morning, neither Castronovo, his representatives nor Journey's official channels had issued a statement detailing what caused the emergency or confirming his condition. TMZ, which first reported on the hospitalization, noted that no public health update had followed overnight, even as fans and fellow musicians flooded social media with well wishes.

The uncertainty now hangs over Journey's next scheduled stop: a Saturday-night show at San Antonio's Frost Bank Center, part of the same farewell run. It remains unclear whether Castronovo will be well enough to perform or whether Toomey will again fill in behind the drums. Castronovo, who first joined Journey in 1998, left the band in 2015 and returned in 2021 after a six-year gap, has had an on-and-off history with the group — but Thursday marked the first time he has had to leave a Journey stage mid-song for a medical reason since rejoining.
