The career of West Ham United defender Calum Davenport is in the balance.
Davenport's career could be under threat after he was stabbed in the legs, a court was told.
The West Ham player, 26, is in a stable condition in intensive care following the attack at his mother's home in Kempston, Bedfordshire, on Saturday.
Worrell Whitehurst, his sister's boyfriend, is charged with causing grievous bodily harm with intent.
