PSV Eindhoven were dealt a blow when sidelined striker Jurgen Locadia picked up a knee injury while in recovery from a groin injury that has kept him sidelined for a number of months.
This news comes as midfielder Siem de Jong was ruled out of action for up to six weeks after sustaining his own groin injury
A statement from the Eredivisie club read: "Jurgen Locadia has undergone exploratory surgery on his right knee in the St Anna hospital in Geldrop.
"The striker will start working on an individual rehabilitation programme over the festive period and hopes to resume training in January.
"Locadia was sidelined for several months with a groin injury this season. While stepping up his rehabilitation programme, he sustained a knee injury."
The club had earlier posted news of injuries to De Jong, Hector Moreno and Jetro Willems.
"Midfielder Siem de Jong is expected to be out of action for a period of four to six weeks after sustaining a groin injury during PSV’s 1-1 draw with Ajax in Amsterdam last Sunday.
"Hector Moreno ’s hamstring injury is less serious than initially feared. The Mexican defender will resume training after the festive period.
"Jetro Willems will train lightly this week, separate from the group. The left back was taken off as a precaution during the 1-1 draw in Amsterdam as he felt dizzy and faint."
