James Maddison is expected to return from an injury this season.
The Tottenham midfielder damaged a knee in the first stage of their semi-final of the Europa League against Bodo/Glimt.
Ange Postecoglou said after Sunday's 1-1 draw in West Ham that it was 'not promising' for Maddison.
Spurs are still running scans on the full degree of the damage, but it is unlikely that the 28-year-old English international will play again in the three weeks before the end of the season.
It is again an injury for Postecoglou in a campaign full of them.
For Maddison, personal heartache with Tottenham on the edge of the Europa League final.
They are 3-1 against Bodo/Glimt with the second stage in Norway.
The final is in Bilbao in just over fourteen days.
Midfielder Lucas Bergvall suffered an ankle injury on the eve of the first stage that he excluded the rest of the season.
Captain Son Heung-Min has missed the last four games with a foot injury. Son has only trained and is doubt for the trip to Norway.
Dominic Solanke, also forced against Bodo/Glimt, missed the draw at West Ham, but is convinced that he is fit for Thursday.
