"Following further examination and consultation, Andros Townsend is to undergo surgery on his left ankle on Thursday after damaging ligaments during our fixture against Stoke City last Saturday," Tottenham said in a statement on their website. "The injury is likely to sideline the young winger for up to ten weeks."
A period of unavailability of ten weeks would leave Townsend unable to play until the second week in July, by which time England's World Cup campaign in Brazil may already be over. England manager Roy Hodgson is due to announce his 23-man squad for the tournament on 12 May, with England set to open their Group D campaign against Italy in Manaus on 14 June.
Townsend, 22, burst onto the scene with Spurs at the start of the season, forcing his way into the England team and playing a key role in the wins over Montenegro and Poland that secured qualification for the World Cup.
The pacy, left-footed wide player has since slipped off the radar, however, starting only five times for Spurs in all competitions since the turn of the year.
