Bob Weir pitched over and was helped from the stage during the Furthur concert Thursday night (4/25) at the Capitol Theater in Portchester, New York.  He was reportedly transported from the scene in an ambulance.  No information about his condition or the cause of the collapse has been released, but Phil Lesh indicated that the guitarist had injured his shoulder earlier in the day during a workout.  Weir, who had already taken a seat instead of standing during the set, was reported by one source to be '...belligerent and incoherent' as he was helped to his feet and off the stage.  After a brief break in the set, the rest of the band picked up where they had left off, completing an encore of Stella Blue, China Cat Sunflower and I Know You Rider.
