Kevin was then called upon at the last minute to dance the Charleston with Alex during Halloween Week.
Earlier this week, Neil tweeted to his 73,500 followers: “Yes I can’t wait for this week myself @AlexScott will be dancing American Smooth to ‘Ain’t no mountain high enough’.”
Katya Jones’ ex, who has been paired up with a celebrity on the BBC One show for the first time this year, added: “I just need to hurry up and recover.”
A recent episode of Strictly spin-off It Takes Two showed a video of Neil and Alex rehearsing their American Smooth.
Host, Zoe Ball, pointed out Neil was on a crutch and instead of dancing with the former footballer, he was giving her instructions on what to do.
Strictly Come Dancing airs on BBC One at 7pm on Saturday.
