|ESPNsoccernet: UEFA Europa League|
Udinese have suffered a double blow ahead of Thursday's Europa League last 32 encounter against PAOK Salonika with midfielder Mauricio Isla and striker Antonio Di Natale out injured.
Both players got hurt during Saturday's 2-1 league loss to AC Milan.
Tests have now revealed Isla has ligament damage in his right knee, while Di Natale, who is Serie A's top scorer with 17 goals netted so far, has fractured a toe in his right foot.
The club has not confirmed how long the two players will be absent but they are likely to be sidelined for at least three weeks.
