Matija Nastastic could be out for six months after undergoing surgery on a ruptured Achilles sustained in Schalke's win at Werder Bremen.
Schalke's winning start to its Bundesliga campaign at Werder Bremen came at a cost. After the game it was revealed that Matija Nastastic faces a lengthy absence due to a ruptured Achilles.
The Serbia center back lasted just 17 minutes of the impressive 3-0 victory at the Weserstadion on Saturday before limping off and being replaced by Roman Neustadter.
Schalke later stated that Nastastic has undergone surgery, with reports suggesting he could be sidelined for six months.
