Isaac Hanson, the oldest member of the brother band Hanson, was hospitalized in Texas with a pulmonary embolism, his rep said Wednesday.

Hanson, 26, was admitted to Baylor University Medical Center after suffering severe shoulder and chest pains after a Tuesday night show in Dallas, says rep Ken Phillips.

“He underwent several tests throughout the night and has been diagnosed with pulmonary embolism” – a clot in a blood vessel, says Phillips. “Isaac is currently undergoing treatment and will be re-evaluated shortly by doctors.”

After his hospitalization, first reported by the Tulsa World, the band’s show in Tulsa, Okla., was canceled.

In April, Hanson became a first time dad. He and wife Nicole welcomed son Clarke Everett in Tulsa.

Hanson and the former Nicole Dufresne, 22, wed last year.

Umm…. is Hanson still together? Everyone together now..ummmmmmmmmmm booooop……
