There's been a long list of incomers with "masked" poor medical histories .... Gilliver, Britt, Agnew, Munro etc....
 
	but IIRC Jimmy Kerr who had a very bright future  picked up a new career ending injury very soon after joining.
 
	The modern pre contract "medical" with full medical/injury history provided by the "selling" club hopefully negates Agnewlike mistakes in future.
