TS singer Jimin has pulled out of the group's appearance "The Graham Norton Show".
The K-pop band - also now as the Bangtan Boys - are scheduled for a performance on the BBC late night talk show, but the star has had to drop out due to severe muscle pain.
The disappointing news was revealed on Twitter by their record label Big Hit Entertainment, who wrote: "We regret to announce that one of the members of BTS, Jimin, will not be able to take part in the recording of the band's appearance on the "Graham Norton Show".
"On the morning of the day of the recording, Jimin began suffering from severe muscle pain in his neck and back, and received medical attention.
"While Jimin made every effort to take part in the program, including arriving at the studio, the decision was made for Jimin not to take part in the recording due to his condition.
"We sincerely apologise to all of our fans who have been eagerly awaiting the band's appearance on the "Graham Norton Show", and ask for your understanding."
The latest injury comes after bandmate Jungkook was confined to a stool during the group's recent gigs at the O2 Arena in London.
Despite that, the boy band - whose lineup is completed by V, Suga, J-Hope, Ji and RM - are celebrating after smashing social media records and merchandise sales for the venue.
BTS confirmed their sold-out shows via The O2's Twitter account and the news received over 14,000 retweets and 32,000 likes with fans going crazy to secure tickets - making it the most popular announcement in the venue's history.
The "Fake Love" hitmakers played two sold out shows on Tuesday the 9th and Wednesday the 10th of October and were commemorated by the O2 because of the high level of interest brought to the company including 1.8 million homepage views.
