NewsLFC injury update: Robertson, Gakpo, Thiago, Bajcetic, Doak, Bradley and Chambers
The left-back sustained an issue when captaining Scotland last week in their Euro 2024 qualifier against Spain.
Meanwhile, the fitness of Cody Gakpo will be assessed ahead of Liverpool's Merseyside derby meeting with Everton on Saturday after he made a return to training following injury.
Asked about Robertson during his pre-match press conference on Friday, Klopp said: "I think the decision we go towards [is] surgery.
"There was a little chance that he could try without. But after talking to pretty much all experts, it looks like surgery will be the best thing, especially in the long term, definitely. And that means he is out for a while.
"Don't know exactly how long but shoulder surgery is not an easy one. From my experience, you can train pretty quickly again but not football-specific because you have to be careful, challenges and all these kind of things. So, yeah, [he] will be out for a while."
Klopp continued: "[Diogo] Jota was not injured, he was suspended. Diogo is available again if nobody tells me differently.
"Cody trained once with the team, so we have to see how that goes for tomorrow.
"Stefan [Bajcetic] out, Thiago [Alcantara] out. Who else? Ben Doak from Scotland has a little muscle thing, so we have to see but is not available for the weekend. Luke Chambers trains today first time again after a little ligament issue. Conor Bradley still out. That's it."
