GRATEFUL DEAD star BOB WEIR sparked concern for his health on Thursday (25Apr13) after collapsing onstage during a concert in New York.
The rocker was performing with his band Further at the Capitol Theater in Port Chester when he fell to the floor in the middle of a song.
Bandmates and crew members helped him get up and Weir, 25, finished the song from a chair before leaving the stage to seek medical attention backstage.
Bandmate Phil Lesh assured fans that the guitarist was OK but had injured his shoulder and would not be returning.
Furthur are still scheduled to perform in Atlantic City, New Jersey on Saturday night (27Apr13).
