Liverpool forward Diogo Jota will miss the Christmas fixtures after manager Juergen Klopp confirmed his knee injury was worse than first thought.
Jota was injured close to the end of Liverpool's 1-1 UEFA Champions League draw with FC Midtjylland in midweek.
"Yeah, it's worse than we first thought and better than we then thought," Klopp said before kick-off in their Premier League clash at Fulham on Sunday.
"All the potential surgeons had a look on it, no surgery needed.
"But he will be out for a while.
"We don't know exactly but one-and-a-half, two months.
"It's pretty similar with Kostas Tsimikas, by the way. Unbelievable."
Klopp was dealt a further injury blow during the Reds' 1-1 draw at Fulham with central defender Joel Matip withdrawn at halftime after suffering a back problem.
Liverpool are already dealing with long-term injuries to key centre-half Virgil van Dijk and fellow defender Joe Gomez, both with knee issues.
"Joel has a spasm in his back. We will see," Klopp said.
"He will get treatment and we will see. I think there will be a chance for Wednesday (against Tottenham Hotspur)."
Jordan Henderson dropped back to central defence against Fulham, alongside fellow midfielder Fabinho, with Liverpool light on options in that area.
Klopp has been forced to hand appearances to youngsters Rhys Williams and Nathaniel Phillips in recent weeks.
"I hope Joel will be fine, but I don't know," Klopp said.
"We will have to find a solution. That's how the football season is."
