Borussia Dortmund right-back Lukasz Piszczek is set to undergo hip surgery, keeping him out for the remainder of 2013.
Piszczek has been struggling with the injury since as early as February, but had always planned to delay the operation until the end of Dortmund's Champions League campaign.
A mid-June date has now been confirmed for the surgery and the Poland international will not be able to return to training for a further five months after that.
"I can't take it any longer," Piszczek told kicker, adding that the pain had left him with no other choice than to undergo an operation.
Dortmund are reportedly set to sign Greece international Sokratis, who would be able to deputise at full-back during Piszczek's absence.
The Werder Bremen defender, who can also play at centre-back, is close to completing an €8million move to Westfalenstadion within the next few days, according to Ruhr Nachrichten.
Real Madrid loanee Nuri Sahin is also set for surgery but will return in time for the new season. The midfielder needs an operation on his nose after struggling with breathing problems.
Dortmund midfielder Kevin Grosskreutz, meanwhile, has had to withdraw from the Germany squad, who are on tour in the United States, after bruising a foot during the Champions League final defeat to Bayern Munich.
