Manchester City defender Alex Greenwood has undergone knee surgery on a medial collateral ligament (MCL) injury.
The captain was stretchered off in the first half of Man City’s Champions League win over St Polten earlier this month.
Manager Gareth Taylor had initially said the “injury was not as bad as first feared”, but a statement from the club on Thursday revealed that Greenwood required “a repair of her MCL”.
Depending on the severity of the tear, MCL recovery can take anywhere between three and 12 months, with no timeframe given for the defender’s return to action.
Forwards Vivianne Miedema and Lauren Hemp are also sidelined with long-term knee injuries, while Khadija Shaw will not return until January.
Man City were beaten 3-0 by Barcelona – as well as losing to Everton in the WSL on Sunday – in their final game before the winter break to concede top spot in their Champions League group, but had already sealed qualification to the knockout phase.
The news will equally be a significant blow for Sarina Wiegman and England, who begin the defence of their Euros title on July 2. The 31-year-old was a key part of the Lionesses team that reached the World Cup final in 2023.
