King doubtful for Twente test
"We're not sure on Ledley but I'll say he's probably doubtful," Redknapp told reporters ahead of the Group A match. "If he's fit, he'll play, but I'm not sure if he will be fit."
Redknapp said he would make late a decision on the central defender who missed Saturday's defeat at West Ham United after picking up a slight groin problem in training on Friday.
"Charlie (Vedran Corluka) will play at centre-back again if Ledley's not right. I can't see too many changes at the back."
Spurs have a shortage of fit central defenders with Younes Kaboul (hamstring), William Gallas (groin) and Michael Dawson (ankle/knee) all unavailable for the visit of the Dutch side.
However, goalkeeper Heurelho Gomes has recovered from a groin injury that has kept him out since August 28 and the Brazilian could replace stand-in Carlo Cudicini.
"Carlo has played very well and I'll make that decision tomorrow," said Redknapp.
