Sunderland forward Duncan Watmore is set to miss the rest of the season after scans revealed a cruciate ligament injury suffered in Saturday's 2-1 victory over Leicester City.
Watmore, 22, was stretchered off after a clash with Leicester's Christian Fuchs during the win over the Foxes at the weekend.
He has since visited a specialist in London and is now facing an extended period on the sidelines.
Sunderland said in a statement: "Sunderland boss David Moyes has confirmed that Duncan Watmore is likely to miss the rest of the Black Cats' season following the results of his scan on Monday.
