LIVERPOOL: Everton defender Phil Jagielka could be sidelined until January after undergoing a second knee operation, the Premier League side revealed on Saturday. Jagielka, 27, has been off the pitch since damaging knee ligaments in April but had been hoping to return to action before the end of November. However he underwent surgery again on Wednesday on a small cartilage tear and Everton manager David Moyes said his return could now be pushed back. Moyes said that striker Victor Anichebe has also suffered a complication in his recovery from a knee injury.
