James Maddison is not expected to return from injury this season.
The Tottenham midfielder damaged a knee in the first leg of their Europa League semi-final against Bodo/Glimt.
Ange Postecoglou said after Sunday's 1-1 draw at West Ham that it was 'not looking promising' for Maddison.
Spurs are still running scans on the full extent of the damage, but the 28-year-old England international is unlikely to play again in the three weeks before the end of the season.
It is another injury blow for Postecoglou in a campaign full of them.
