Perhaps one of the most famous being Brian Clough.
"Clough’s playing career effectively ended on Boxing Day 1962, when in an accidental collision with the Bury ‘keeper Chris Harker, Clough ruptured the medial and cruciate ligaments in his right knee. He was twenty-nine years old. After a long lay-off, much physiotherapy and an aborted come back, it was clear Clough was no longer the player he was, having lost much of his pace and strength on the ball. His vision, drive and skill were never diminished, but he – and his club – had to face the facts. His playing days were over."
