TT legend Keith Amor has been forced to retire from racing after a visit to his surgeon revealed the shoulder he injured at last year's Isle of Man festival hasn't healed sufficiently enough to allow him to continue.

The Falkirk man fell at Quarterbridge and Union Mills in 2011 and then aggravated the acromioclavicular damage with a crash at the Ulster Grand Prix later in the season. He had expected the joint to heal better after extensive surgery to re-build it but it hasn't done so.

“Unfortunately even though I have had the first round of operations, there is still damage that is resisting treatment. My right shoulder is proving difficult to keep under control," he told The Belfast Newsletter.

“The left shoulder is less trouble but it's painful and in need of more treatment. Because of my ongoing injury problems I've decided to retire completely. My decision has been a difficult one and one which I have agonised over for the past three months."
