Leicester defender Ricardo Pereira will be out for another two weeks with the groin injury he sustained on his comeback appearance.
The Portuguese right-back returned from a nine-month absence with knee ligament damage against Zorya Luhansk in the Europa League on Thursday.
However, he had to be substituted at half time in Ukraine after complaining of a groin problem.
Foxes boss Brendan Rodgers provided an update on the 27-year-old, and fellow defender Caglar Soyuncu, following his side’s 2-1 win at Sheffield United in the Premier League on Sunday.
“Ricky has a slight, not a serious, issue with his groin, but probably one that will keep him out for 10 days to two weeks,” said Rodgers.
“It was unfortunate. The surface was very slippy and he’s just aggravated his groin, but hopefully it won’t be too long.”
Soyuncu also suffered a groin injury in Ukraine last week on his comeback. The Turkey international’s return from injury lasted just 16 minutes before he had to be replaced.
Rodgers said scans have shown that the recurrence of the groin problem that had sidelined him since October is not as bad as initially feared, but he did not put a time scale on the 24-year-old’s absence.
“Cags, it’s too early for him to come in, but thankfully it’s not as bad as we first thought,” said the Foxes boss.
“He’ll be out with the medical team next week, and we’ll monitor that, but hopefully it won’t be too long.”
