DANCING On Ice star Brian McFadden is looking "unlikely" to skate on this weekend's show after ongoing issues with his his shoulder injury.
It comes after the former Westlife singer, 38, fell on his back last month and badly damaged his rotator cuff.
He has been struggling in training this week and has been in and out of physio with his ongoing back problems.
A backstage source said: "Brian has been throwing himself into training but is finding it really tough as his back is giving him issues. He has been to see the show's physio, but it's looking increasingly unlikely that he will have to pull out of the show.
"Obviously he's determined to keep trying but he knows there's only so much he can do without inflicting a serious injury and causing long-term damage."
It comes after bosses have had to defend the show's safety record - after one of its pro skaters questioned why celebs would want to sign up.
Last week Corrie star Jane Danson fainted on the ice, Ryan Sidebottom had a groin strain and Gemma Collins' numerous falls.
After being voted off on Sunday, Saira Khan's ice partner Mark Hanretty said: "What worries me is getting celeb line-ups for the future.

"When (accidents) continue to happen, it's like, 'How can they continue to advertise it as a job to any future celeb?'
"Like, 'Yeah, come and join this show, you could faint, whack your chin open, end up in surgery having a dislocated shoulder ... ' There are many eventualities."
A spokesman for the ITV show said: "Brian has a bad back and is currently being monitored by our show physio."
