Westlife Instagram already explained on February 29 that Mark had to undergo surgery a few times between 2020 to 2023; this forced him to miss a few shows in late 2022 and May 2023 (worst of all before his birthday!!). He developed an incisoral hernia in late 2023 and underwent successful treatment, but doctors advised him against touring, as he needed more time to recover. So Mark made the difficult decision to step down from live performances, and was forced to miss the North American dates this month.
