Tom Fletcher is ‘gutted’ for missing.
Tom and pro partner Amy Doden had contracted the virus and needed to be isolated before returning for three weeks of competition.
Musician Tom Abesgold is filling out for the band’s live shows, and Tom has appealed to fans to follow him.
Speaking in a video on Instagram, he said: “Thank you so much for your messages, I’m fine. It means I’m isolated and I can’t finish the McFly Tour, which makes me very happy. Sorry, I’m very upset.
“But the shows do go on. You guys have been up all night waiting for MacFly entertainment that I know Danny, Dougie and Harry are able to give you … without me there.”
“Obviously it wouldn’t be so good without me, but it would be a McFly show. If you have tickets for the last two nights, go and have a great time, sing your heart out.
“We have a good friend called Tom, he stands up for me, he’s been a fan of McFly since he was five, so it’s amazing he’s been a part of McFly for a couple of nights. Yes, thank you, Tom. “
