NEW YORK Guitarist Bob Weir fell onstage while strumming his guitar at a concert in Port Chester, N.Y.
Video posted online shows the 65-year-old musician collapsing Thursday night during a performance with Furthur. He was quickly helped off the floor as the crowd cheered him on.
Weir is on tour with Furthur, the band he formed with fellow Grateful Dead member Phil Lesh.
Lesh told the crowd Thursday that Weir had been suffering from a strained shoulder.
A representative for Furthur didn't immediately respond to an email seeking comment. The band's next show is scheduled for Saturday in Atlantic City, N.J.
