Bob Weir, Grateful Dead Guitarist, Collapses On Stage [VIDEO]: Rocker Falls During Furthur Concert, Blames Strained Shoulder

During a Furthur concert in Port Chester, NY on Thursday evening (April 25), former Grateful Dead founder and guitarist Bob Weir stumbled and collapsed on stage during a live performance of "Unbroken Chain." Following the onstage fall, 65-year-old Weir wobbled into a chair and finished off the song before leaving the stage. Later on, bassist Phil Lesh announced to the crowd that Weir's shoulder was extremely strained and the pain is what caused him to stumble to the floor.

In the fan-made video, Weir can be seen stumbling off-balance just moments before collapsing during the live set (keep an eye out around the 45-second mark):

Shouts can be heard from the crowd and crew members rush on stage to help Weir. The band continues playing as Weir is quickly brought to his feet and escorted into a chair on the far left of the stage - that's when the crowd begins to cheer. The song ends several minutes later and Weir then exits the stage.

Fellow members of the popular Grateful Dead spin-off band helped Weir offstage to make sure he was okay. Once they returned, former Dead bassist Phil Lesh told the fans that a strained shoulder was bothering Weir. They went on to finish the show without him.

No other details are yet available, although the Furthur's scheduled to play in Atlantic City, NJ Saturday night.
