Real Sociedad striker Inigo Diaz de Cerio has been ruled out for the next six weeks.
The promising young hit-man suffered a knock in training and scans have now confirmed that he has torn a muscle in his right knee.
Diaz de Cerio will undergo surgery on Friday, with news of his absence only likely to compound the air of gloom that hovers over the Basque club.
Sociedad are currently in the relegation zone having yet to pick up a victory this season, as a congested treatment room shows few signs of emptying.
At present the likes of Adriano Rossato, Morten Skoubo, Dalibor Stevanovic, Igor Jauregui and Fabio Felicio are all currently sidelined.
