Everton could be without Dominic Calvert-Lewin for their Premier League game against Liverpool, reports the Liverpool Echo.
The 25-year-old was withdrawn 62 minutes into last weekend’s 1-0 league win over Arsenal.
Calvert-Lewin will now be assessed by the medical staff at Finch Farm early this week.
The Englishman has struggled with his fitness for the past 18 months, which has affected his productivity.
Everton manager Sean Dyche revealed after his first game in charge that Calvert-Lewin had been suffering from a hamstring issue.
The Toffees face Liverpool at Anfield on February 13 and could be without the England international.
The Reds lost their seventh league game of the season to Wolverhampton Wanderers on Saturday.
They will be keen to bounce back in the Merseyside derby, but Everton have a chance of an upset.
Neal Maupay replaced Calvert-Lewin against Arsenal and could start against Jurgen Klopp’s side.
James Tarkowski provided the only goal against Arsenal, heading in Dwight McNeil’s corner.
The Goodison Park club will not rely solely on their forwards to get goals under Dyche.
Calvert-Lewin has scored six league goals for Everton since the start of last season. He bagged 29 league goals across 2019-20 and 2020-2021.
They could do with that version of the former Sheffield United striker this term. The Blues have scored 16 league goals in 21 games this season.
They remain in the relegation zone despite the hard-fought win over the league leaders.
A victory over Liverpool would be massive, and Dyche will fancy his team’s chances.
