Football - Soccer-West Ham's Diame faces three months out with hamstring injury

LONDON, Dec 9 (Reuters) - Senegal midfielder Mohamed Diame faces a possible three-month layoff after injuring his hamstring in West Ham United's 3-2 Premier League defeat by Liverpool on Sunday.

Diame was carried off on a stretcher after 73 minutes having pulled up and fallen to the ground clutching his hamstring.

"Not good, it does not take a medical expert to know it is a serious hamstring tear when he falls and stopped the way he did," West Ham manager Allardyce told reporters.

"I would expect, in medical terms, for it to be a grade 3 (injury) and that could be anything up to eight, 10 or 12 weeks."
