Finalist White with the show's host, Cat Deeley
So You Think You Can Dance finalist Robbie White has been forced to pull out of the show after he dislocated his shoulder during a practice session.
White, one of four finalists, was told the injury could take months to heal.
Previous contestants will step in for White on partnered dances. The remaining three finalists are Lizzie Gough, Tommy Franzen and Charlie Bruce.
The winner of the BBC One Talent show will get £100,000 and the chance to perform on the US version of the show.
Talking about his injury, White said: "A blinding pain hit me before I even hit the floor. It was instant. I knew from how hard I went down.
"It wasn't 'til I was in the ambulance on the way to the hospital, when the pain medication kicked in and my head cleared, that I knew something serious had happened."
"The doctor said it would probably be months before I could move the arm again," he added.
"As a dancer we know what our bodies can do, and I will push to be back and fit and dancing as soon as I can."
Saturday's final is the culmination of a seven-week search for the UK's favourite dancer.
"It will be very hard being there and not being part of it," said White "But I definitely want to be there, to come out and have a chance to say my piece, say thanks."
