Everton's Kevin Mirallas and Tony Hibbert will be sidelined for "a few weeks" through injury, manager David Moyes has confirmed.
Belgium international Mirallas suffered a recurrence of the hamstring injury that previously kept him out of action for a month in last week's win over Tottenham.
And after struggling with a calf problem all season, Hibbert will undergo surgery to solve the ongoing injury early next week.
Moyes said: "It looks like we'll lose Kevin for a few weeks. It's a really big blow - anyone who watched the game last week can see that.
"His hamstring isn't right so it looks like we'll have to take more time over it so it will probably keep him out for a while.
"We thought we had managed it because it was quite a mild hamstring injury
which we gave extra time because I was expecting him to be available for the midweek Arsenal game.
"I then didn't use him in the Manchester City game in the hope he would be right for the Tottenham game so we gave him extra days to make sure it was right.
"We will now have to take even more time, unfortunately, and it will be a big miss for us because he gives us a different attacking dimension from what we have and he'll be a loss.
"Tony Hibbert has a recurrence of his calf injury so he is going to have an
operation on Monday which will keep him out for a while."
