Tottenham boss Harry Redknapp is facing a defensive crisis after losing Ledley King and Sebastien Bassong during the 3-0 defeat to Chelsea at Stamford Bridge.

King was substituted because of a hamstring injury on, and Bassong left the field with concussion after falling awkwardly in a collision with Nicolas Anelka in the Barclays Premier League match.

Spurs are already without injured central defenders Jonathan Woodgate and Michael Dawson and now King, who does not train with the squad during the week because of a long-standing knee problem, may be out for six weeks.

"Ledley has done his hamstring," Redknapp confirmed.

"He's the most fantastic person and player - and he's so important for us - but if you don't train you can't just go out and play without doing hamstrings, groins or calves.

"Bassong doesn't look too good, either. He got a bang on the head, and his eye's all swollen up. It doesn't look too clever at all. The doctor took him to hospital with concussion.

"Woodgate's nowhere near playing again. He went to see a specialist again on Saturday and he just can't train.

"We haven't got to the bottom of the injury at all, what's causing him discomfort. Dawson has a chance - he's the one."
