Tottenham star James Maddison is said to be a doubt for the preseason after the knee injury that has ended his campaign.
Mail Sport reported on Monday that Maddison would probably not play again this season after damaging a knee in the first stage of their Europa League semi-final against Bodo/Glimt.
Ange Postecoglou said after Sunday's 1-1 draw in West Ham that it was 'not promising' for Maddison.
According to the BBC, the Maddison knee injury is expected to be expected to keep the English international out until July.
The midfielder is said to have no surgery and has sustained suspected ligament damage.
Although Maddison is expected to be a doubt for the start of the preseason due to the recovery time of three months, the 28-year-old fit must be on time for the start of the new campaign.
The loss of Maddison is a big blow to Tottenham's hope for success in the Europa League.
Maddison has been influential in the competition in front of Ange Postecoglou and scored their second goal in the 3-1 semi-final first leg victory over Bodo/Glimt last week.
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.
