It has just been announced that all upcomingdates have been cancelled. This includes the band’s summer and fall dates as well as a destination event in Jamaica.

Here’s the full text of the statement via Furthur Facebook:

Circumstances have necessitated that all scheduled tour dates for Bob Weir & RatDog are being cancelled. This applies to all dates on the summer tour starting on Thursday, August 14 in Boston through September 14 in Nashville and also includes the Jamaica event in January of 2015. Full and complete refunds are available at place of purchase. We sincerely apologize for any inconvenience.

No further details have been revealed. Weir’s commitments include appearances at the Peach Music Fest, Lockn’ and Phases Of The Moon. It will be interesting to see what these festivals come up with to replace Bobby at their events, especially Lockn’ who were counting of the guitarist for two headlining sets with RatDog as well as a one-night-only Furthur reunion set. We also await word from the Chris Robinson Brotherhood, who were set to open many RatDog dates this summer.

Last month Weir missed a RatDog show that went on without him in Las Vegas, but was able to return for the next night’s show. Bobby was also unable to finish a a Furthur show in Port Chester in April ’13 that led him taking a few months off. Our thoughts and prayers are with Bobby and the RatDog family in regards to whatever they are dealing with.

Update: Lockn’ organizers are offering a refund through 5 p.m. ET on Wednesday, August 13. Ticketholders must email tix@musictoday.com with their refund request. Meanwhile, Peach Music Festival organizers are offering refunds to those who purchased single day tickets for Friday, August 15 and don’t want to attend anymore. Those who would like to request a refund can do so through Wednesday, August 13 at 5 p.m. ET by either emailing tix@musictoday.com or calling 1-800-594-TIXX.

John Scher, whom Rolling Stone refers to as Weir’s manager (we believe he’s Bobby’s former manager), told the magazine “I love the guy and wish nothing but good health. He’s an extremely talented and very underrated musician. He’s an important guy. Bobby’s been having health problems for a while and now there are plenty of people who support him and want to help him get the care he needs.”
