Ghana midfielder Prince Buaben could be facing a spell on the sidelines after limping off Heart of Midlothianââ¬â¢s 2-1 win over Ross County in the Scottish Premier League.
Buaben, who was key in midfield for the Jambos, walked off on 54 minutes.
He is expected to undergo tests on Monday morning to ascertain the severity of the damage.
Buaben has been one of Heartsââ¬â¢ key men on their return to the Scottish top-flight this season.
