Cambridge United have cancelled the contract of new signing Steven Connors after just five weeks at the club. In one of football's more unusual transfers, the midfielder has been released before making a competitive appearance for the club. Cambridge claim the player had a pre-existing medical condition which he deliberately withheld from them when they signed him from Fleetwood in June. They have now terminated his contract claiming that he should have told them about the condition, which has not been named, before he signed for them. The U's released a statement which said: "This particular pre-existing condition was impossible to detect as the player had not undertaken physical activity over the summer months. "As Steven withheld vital information about his medical history and an ongoing condition the club was left with no alternative but to terminate his contract." Connors has been struggling with a groin injury throughout pre-season so far, although neither party has confirmed that it definitely was the groin problem that he failed to mention in the medical. All-in-all he has enjoyed a shortlived stint at a club to put even Robbie Keane to shame. The 25-year-old now has the unenviable task of finding himself a new side when any football club who bothers to Google him before handing him a contract will find out that he allegedly has a secret medical condition that he doesn't like to tell you about during his medical. We don't want to heap further doom and gloom on Connors, but we don't fancy his chances. It has to be up there with the very best of short stays a football club and also one of the most bizarre reasons for the short stay. Do you have any favourites? Who has been through the revolving door at your club and why did they leave just as quickly as they arrived?
