Gylfi Sigurdsson will see a specialist on Monday evening after he sustained a knee injury in Everton's Premier League win over Brighton on Saturday.
A statement on Everton's website said it is anticipated that the 28-year-old could be out "for several weeks". However, a definitive time frame will only be known after he consults with the specialist.
Sigurdsson received treatment after picking up the injury in the first half of the game but played on until the end of the match.
His brother Olafur Mar Sigurdsson has spoken to Icelandic media in which he claims the joint of the right knee is damaged.
"Gylfi Sigurdsson will see a specialist this evening to determine a time frame for recovery from the knee injury he sustained in Saturday's Premier League win over Brighton at Goodison Park," Everton's statement said.
"It is anticipated that the 28-year-old Icelandic international could be sidelined for several weeks but it will only be after consulting with the specialist that a definitive time frame will be known."
Everton's club-record signing endured a difficult start to his Toffees career having moved from Swansea in the summer as his struggles were matched by the team's.
His fortunes have improved since Sam Allardyce replaced Ronald Koeman in late November, scoring five of his seven goals in his 17 matches since then.
