Dominic Calvert-Lewin is a doubt for Everton’s match against Newcastle United on Thursday.
The Toffees were beaten 1-0 by Wolves at Goodison Park yesterday.
Injuries have hampered Calvert-progress Lewin’s this season, and he has appeared in just nine games.
However, the England international was unable to play against Wolves due to an illness.
On goal differential, Everton are just above the Premier League relegation zone ahead of their match against Newcastle.
Frank Lampard, on the other hand, couldn’t say for sure if Calvert-Lewin would return.
The Blues boss said: “He’s not well so we’ll see.”
Frank Lampard has urged Everton to have a positive attitude following Sunday’s 1-0 defeat against Wolves in the Premier League.
“We were the stronger team in the first half, but Wolves don’t give you many opportunities, which is why they don’t concede a lot of goals,” said Lampard.
“If we’d scored one of our early chances, it would have looked and felt a different game.
“Their goal changed the feeling of the game and the feeling of the stadium, which is understandable, with the position the Club is in.
“It is disappointing because everyone feels the need for points, which is normal, but we have 12 games remaining and can’t look at this one alone.
“We lost to a good team in a tight match, with 10 men at the end of the game, when we wanted to push.
“My job is to give confidence to the players, to create a mentality where we are together and understand what we all want, which is to stay up.
“The important thing for us is to have the absolute desire and fight to get out of this.
“It has been a long time the players haven’t won games, it is impossible to change that overnight, without working and fighting for something to go in your favour.
“The more we fight and stay together, then something may go in our favour that changes the look of it [Premier League table] very quickly.
“We have to keep working to be the team [in lower reaches] that gets the right results.”
