Dejan Kulusvski has undergone a knee operation and will not play in the Europa League final.
This is the last blow to Tottenham which is already without creative fields James Maddison and Lucas Bergvall for the force test with Manchester United in Bilbao on Wednesday.
Maddison and Bergvall will not play again this season and although the Spurs have not specified a delay for the absence of Kulusvski, his season is also the most likely to be finished.
The 25 -year -old Swedish international was the best Tottenham player at a certain distance during the first half of the season until February when a foot injury excluded him for six weeks.
He has not resumed the same form since and was selected to start against Palace, when most of the first team was rested, in the hope that it could help him find his pace.
Kulusevski only lasted 19 minutes before having to be replaced and, although the Postocoglou angel boss said that he hoped that it was nothing more than a blow, he turned out to be more serious.
Dejan Kulusvski will undergo surgery on an injury suffered during the defeat of the spurs by the palace
Spurs did not put any
Maddison damaged the knee ligament during the first stage of the Europa League semi-final against Bodo / Glimt and is expected to be released for three months. Bergvall injured an ankle by training the day before the same game.
This leaves Postcoglou short of specialized field environments. Rodrigo Bentancur, Yves Bissouma and Pape Matar Sarr are his main options. Archie Gray, 19, will also enter the equation.
