Paracyclist Rachel Morris 'worried' for shoulder after crash
British paracyclist Rachel Morris has already lost both of her legs to a condition which causes her body to reject injured limbs.
So when she dislocated her shoulder in a training accident last month, she admits she became "very, very worried" about losing her arm, too.
BBC Sport followed Morris to paracycling's Road World Championships in Denmark, to see if she could defend either of her world titles despite her injury and her fears.
