ROCHESTER, Minn. (AP) — Comedian Gallagher is hospitalized in Minnesota after collapsing during a performance.

Todd Powers, owner of Whiskey Bone’s Roadhouse in Rochester, said the 64-year-old Gallagher collapsed in the middle of a show there Thursday night.

Gallagher’s manager, Craig Marquardo, says the comedian is in stable condition and will be hospitalized overnight. He says he doesn’t yet know what caused Gallagher to collapse.
