The 35-year-old, who had a show scheduled in Middleton, Manchester, on Thursday 8 September 2016, took to Facebook to explain his absence.
“My daughter had a nasty head injury at her aerial dance class and I had to rush her to A&E,” he explained.
“I didn’t know how serious it was or how long it would take, or even if I’d be in the right headspace to do a gig so I thought it was best to just cancel.”
Manford assured fans that his daughter is now “totally fine”, adding the incident was a bit of a “scare” for him.
“I will look at the diary for a possible replacement date but in the meantime please contact the box office who will reimburse tickets,” he wrote.
“Thanks for being so understanding, you know I would never do it if it wasn’t a genuine emergency.”
Fans were understanding of his situation.
“Mate I love that you’re a big celeb but when the shiz hits the fan, you’re a parent,” one person wrote.
Another commented: “People should totally understand. Family always comes first. Well done.”
Manford has seven-year-old twin daughters, a five-year-old daughter and four-year-old son with his former wife Catherine Manford. He also has a one-year-old daughter with his current partner Lucy Dyke.
He did not state which daughter sustained the head injury.
