Tottenham boss Harry Redknapp admits concern for Ledley King in retirement.
Already without long-term injury victim Michael Dawson, the Spurs boss lives with constant worry that King's career could suddenly end if he keeps playing without training.
"Only Ledley will know when he's had enough," said Redknapp.
He wants to play and we can't stop him. In the long term, of course, I worry. I don't want to see him end up as a cripple. Playing football is one thing but they can have ops and knee replacements now and he might need something like that."
