The singer and drummer had to seek medical treatment after hurting himself during the duo's show in Norwich, England on Wednesday (18Nov15), and now he has bowed out of plans to play at Glasgow's O2 ABC venue with bandmate Laurie Vincent.

A statement posted on Facebook.com on Thursday reads: "During last nights (sic) show in Norwich unfortunately Isaac was badly injured on stage. He was seen immediately by doctors in hospital, and today was seen by a specialist who confirmed that along with dislocating his shoulder there is serious tissue damage that requires him to rest his arm to avoid permanent damage.

"Given that he can't move his arm or drum, unfortunately we have to cancel tonights (sic) show in Glasgow and are looking into rescheduling the date asap (as soon as possible).

"Sorry for the inconvenience to anyone who bought tickets and thank you all for your ongoing love. More details to follow soon."

It is not yet known if other dates on the pair's ongoing U.K. tour will be affected by the injury. Slaves are scheduled to perform across England until the end of the month (Nov15), while they are also booked for two more shows in and around London in December (15).
