Aston Villa have confirmed that the England international will miss a further 12 weeks with the injury he picked up in last weekend's draw against Wigan Athletic
The 28-year-old had looked set to feature for England in Poland and Ukraine after securing a regular place in the international set-up following the 2010 World Cup.
However, despite undergoing a successful operation on his ankle on Monday night, Villa have revealed that he is set to miss a further 12 weeks with the injury.
A statement on the club's official website read: "Darren Bent underwent surgery tonight in a London clinic to repair ruptured ligaments in his left ankle.
"The operation was a complete success and it is expected that Darren will be able to resume full training in around 12 weeks."
Bent, who is Villa's top scorer with 10 goals this season, sustained the injury in the club's 0-0 draw away to Wigan Athletic last weekend.
