AJ PRITCHARD and dance partner Saffron Barker's performance on this week's Strictly Come Dancing could be hanging in the balance.

A back injury for Saffron had raised concerns among viewers that the social media star and Whitchurch professional dancer, AJ, may not make an appearance on Saturday for week five of the hit BBC One show.

The pair had to call off training earlier in the week due to Saffron suffering with back pain, as she took to Instagram to update her followers.

The 19-year-old took to the social media platform to inform her fans that she was struggling with the injury and had pulled out of a training session.

"The pain in my back is just keeping me up all night," said Saffron on Instagram.

But the 19-year-old was quick to update everyone during the week and said that she wasn't ready to give up.

"You've probably all seen that I've got an injury with my back," said Saffron.

"My rib has twisted so therefore all my muscles are having spasms however, we're still going and I'm feeling much better than day one and two. Wouldn't give up for anything."
