Leicester City defender Caglar Soyuncu could be out for three months with an abductor injury, manager Brendan Rodgers says.
The centre-back, 24, missed Sunday's defeat by Aston Villa with the groin injury, picked up on international duty with Turkey.
He had started the Foxes' four previous Premier League matches and played 34 of 38 league games last season.
Rodgers said the Turkey international would be a "big miss".
"The muscle is right off the bone, so he could be up to three months, which is an absolute shame for him," Rodgers said.
