Tottenham facing defensive dilemma ahead of FA Cup semi-final

Harry Redknapp will wait until the last minute before choosing his Tottenham side for Sunday's FA Cup semi-final against Portsmouth, with injury concerns causing a serious selection headache, particularly in the centre of defence. The Spurs manager could be without seven potential centre-backs at Wembley this weekend. Of Redknapp's preferred options to partner Sébastien Bassong, Michael Dawson faces a fitness test on an achilles injury, Jonathan Woodgate is out for the season with a groin injury and Younes Kaboul, a former Portsmouth player, is cup-tied. Ledley King has thigh and knee problems, but Redknapp is unsure of his availability. "You never know with Ledley," he said. "He doesn't train, he could play." Tottenham's makeshift options are also thin on the ground. Vedran Corluka, who could move inside from full-back, has an ankle injury, as does Tom Huddlestone, who could move into defence from his usual midfield position. Kyle Walker, who can play in central defence though is normally utilised at full-back, is also cup-tied. His absence could see Benoît Assou-Ekotto move from left-back to the right side of defence. Redknapp had no better news with regard to Aaron Lennon. The England winger has not played this year due to a groin injury and though he returned to training on Tuesday is not ready for this weekend. "He's not fit," said Redknapp. "We're just taking it day by day with him."
