"I am so sorry for any inconvenience that I have caused to the fans who bought tickets," the actor-musician wrote.
Kiefer Sutherland has postponed the last three shows of his European tour after he seriously injured himself falling on the stairs of his tour bus.
The "24" star recalled the horrible accident on Instagram Thursday and explained why he wouldn't be able to perform at the final stops of his tour in Denmark and Sweden.
"Sadly I slipped on the steps of the bus whilst travelling to Denmark and seriously injured a rib, making it difficult to breathe and impossible to sing," Sutherland wrote in a message. "Regretfully, I will not be able to perform the last 3 shows of our tour, but have every intension [sic] of making up these shows in September / October when we return."
"I am so sorry for any inconvenience that I have caused to the fans who bought tickets," he added. "I will do everything I can to make it up to you. Thank you for your understanding. Sincerely, Kiefer."
The musician reiterated in the caption that he would definitely be performing make-up shows later this fall.
"Make up dates in September to be announced shortly for Denmark and Gothenburg," he wrote. "My sincere apologies. Kiefer."
The "Designated Survivor" star released his second country album "Reckless & Me" back in April and has been promoting the music on his nationwide and European tour.
Although Sutherland is best known for acting, he says he's been writing songs since he was 15.
"Music was something that I became really seriously attached to as a really young person because I had an older brother who I idolized and he was the biggest music fan in the world," he told People in 2016.
"I just wanted to be exactly like him," he added. "I made the joke that I was probably the only third grader that was listening to Aerosmith, so country music was not the music that I certainly grew up on."
Sutherland released his debut album "Down in a Hole" back in August 2016. The star joked at the time that he was hesitant to transition into music because many actors have done the same before him.
"I had no intention of making an album," he told People. "I hear about an actor wanting to do music and my eyes roll back too. I'm completely aware of the stigma and that's why I never did it."
