Bob Weir left the stage early last night (April 25), during a set by Further at the Capitol Theatre in Port Chester, New York.
According to music website jambase, Weir was seen struggling throughout the show and was eventually helped into a chair onstage by two crew members.
The band left the stage, returning without Weir.
Bassist Phil Lesh explained to the audience that Weir had suffered a strained shoulder earlier that day.
As members of the Grateful Dead, Weir and Lesh played the Capitol Theatre 18 times between 1970 and 1971.
