Everton goalkeeper Jordan Pickford is reportedly in a race against time to return from injury before the end of the campaign.
The 27-year-old aggravated a muscle injury in last week's defeat to Burnley and has been ruled out for an initial period of two weeks.
However, The Sun claims that the damage could be worse than first feared, with Pickford possibly spending the next six to nine weeks on the sidelines.
That would see the England international miss the majority of Everton's remaining 10 Premier League games, while also making him a fitness doubt for his nation's Euro 2020 campaign.
England face Austria in the first of their pre-tournament friendlies on June 2, with the Three Lions' campaign beginning 11 days later.
The report indicates that Gareth Southgate will not use Pickford unless he is 100%.
