Tottenham manager Andre Villas-Boas has confirmed Benoit Assou-Ekotto faces a month on the sidelines with a knee injury.
Villas-Boas, who claimed his first league win as manager of Spurs with a 3-1 victory over Reading on Sunday, was forced into playing Kyle Naughton at left-back for the trip to the Madejski Stadium, and subsequently revealed his reasons for the change in his post-match press conference.
"Benoit has a small fragment in his knee that makes his knee swell a lot, and he has played through pain in the last couple of games." he told reporters.
"He's probably going to have his knee washed up and if that happens we are looking for a four-week absence."
Naughton is now likely to deputise for the Cameroon international with back-up left-back Danny Rose loaned to Sunderland for the season.
