Brendan Rodgers has confirmed Mamadou Sakho is set for a spell on the sidelines due to a thigh strain.
The manager expects to be without Liverpool's No.17 for 'two to three weeks' after he sustained the problem and subsequently missed the Champions League trip to FC Basel.
Rodgers told reporters at a press conference at St. Jakob-Park: "It's pretty much the same as we were at the weekend apart from that Mamadou Sakho is not here - he has a slight strain, which may have him out for a few weeks.
"His injury came in a training session. It's unfortunate - he's just felt a pain in his thigh. He went and had a scan on it which showed he's got a slight tear in there, which will be probably two to three weeks."
Liverpool touched down in Switzerland shortly after 3pm local time ahead of Wednesday's Champions League Group B encounter with Basel.
Offering an update on the fitness of the rest of his squad, Rodgers insisted he will call upon the services of a similar group of players to the one he had at his disposal against Everton on Saturday.
"Apart from that [Sakho], the squad is pretty much the same [as against Everton]," he said. "Daniel Sturridge isn't quite available and the others that have been out are still out.
"It doesn't leave us short, we're working with what we've got. We always felt after this next international break we should have everyone back and the group will be up to full strength again.
"We've got some young players who've travelled with us, so it's a good experience for them."
