Jamaal Lascelles was limping badly during Newcastle United’s last match in the FA Cup.
Lascelles picked up a knock in Newcastle’s last match against Blackburn Rovers, which left him hobbling badly.
The Magpies defender tried to play through the pain, but ultimately had to be taken off.
But Benitez does not expect that Newcastle will be without their captain for too long.
“Jamaal, it seems, was feeling his hamstring,” he said.
“We will see. It seems that it was not very serious, but he couldn’t carry on. In a couple of days we will have a better idea. At the moment, it’s too early.”
Newcastle will certainly hope that Lascelles is not sidelined for long, as they need everyone fit right now.
Newcastle are struggling badly in the Premier League, and currently sit in 18th place in the standings.
The Magpies did make it through in the FA Cup though, as they beat Blackburn 4-2 in extra time.
Newcastle’s next match comes against Cardiff City at St. James’ Park on Saturday.
