Liverpool defender Martin Skrtel has a broken metatarsal in his right foot.
The 25-year-old Slovakian international was stretchered off during his team’s 3-1 win over Unirea Urziceni in the Europa League on Thursday.
Liverpool boss Rafael Benitez said: “It was a good result but then we had the bad news about Martin.
“He’s had X-rays and they confirmed he has a broken metatarsal. We have to check over the next couple of days how long it will take to recover.”
There was better news from Benitez about Skrtel’s fellow defender Glen Johnson.
The £17m signing is nearing a comeback, having not played since late December because of a knee injury.
“He’s doing well. He was training today with the team – a light training session,” said Benitez.
“I was watching him and he was quite sharp but Sunday will be too soon.”
