Everton's top scorer Louis Saha is likely to miss the rest of the season after an ankle operation.
Saha, scorer of 10 goals this term, was injured in the Premier League win over Fulham a fortnight ago and joins two other key players in Mikel Arteta and Marouane Fellaini on the sidelines. Jack Rodwell, Tim Cahill and Seamus Coleman are also doubtful for today's game with Aston Villa at Goodison Park after withdrawing from recent international duty.
Manager David Moyes said: "That is the way football is, you get injuries. We have got a fair spate of them at the moment."
