AC Milan's Ghanaian midfielder Michael Essien is facing two weeks on the sidelines after suffering a thigh injury, the Serie A side announced.
The 31-year-old, who replaced Sulley Muntari halfway through Milan's win over Chievo last weekend after his compatriot suffered an ankle knock, will undergo further tests in ten days time.
A statement by Milan said: "AC Milan wishes to communicate that Michael Essien has picked up an injury to his right thigh. The player will undergo further tests in ten days time."
Milan travel to Genoa on Monday looking for a third consecutive win although the Rossoneri are staring at no European football next season.
Clarence Seedorf's side currently sit 11th, 39 points behind leaders Juventus, 22 behind third-placed Napoli in the final UEFA Champions League spot and seven behind Inter who occupy the final UEFA Europa League spot.
