Andy Johnson has picked up a knee injury and is a doubt for Everton's clash with Tottenham on Wednesday.
The Toffees are looking to make a late push for the European places, but their prospects are being hampered by a raft of injuries.
Manager David Moyes has already seen Andy van der Meyde, Nuno Valente and James McFadden enter the treatment room and Johnson is the latest player to pick up a knock.
Everton are hopeful the injury is only minor, but he is doubtful for the visit of Spurs.
"He is a doubt for the game," Moyes told Sky Sports News. "We have the likes of Andy van der Meyde out, Nuno Valente out, James McFadden out, so we are a little bit short.
"We will have a fitness test on Andy tomorrow, but he is certainly a doubt for the game.
"He picked up an injury in training, a little knee injury and we just need to keep an eye on it."
Everton's gaze is firmly trained on Europe, but Moyes admits their priority at the start of the season was to avoid the drop.
"My first objective was making sure our points total would keep us in the Premier League," said the Scot. "Now I have to see if we can push on. The group of players are good enough to do so.
"We are going to have to work very hard, however.
"We need to go on a good run between now and the end of the season to achieve that."
