Liverpool winger Alex Oxlade-Chamberlain will not feature against former club Arsenal in the Community Shield.
The former Gunner has been ruled out for the entirety of pre-season with a knee injury.
Liverpool are currently in Austria on a pre-season training camp and Chamberlain will miss the rest of the Reds' summer sessions as well as the Community Shield with FA Cup winners Arsenal on August 29.
The 27-year-old was injured during training following a challenge from a teammate.
As a result, Oxlade-Chamberlain has now returned to Liverpool for treatment as he looks to recover ahead of the new season.
“Really unfortunate," Klopp told Liverpool's official club website.
“It looks like it is very similar to what Hendo had, which keeps him out for we don’t know for sure exactly how long, but for sure this pre-season he will not make a game, Arsenal for sure not and then we will see.
"The next game is probably two weeks later, but I don’t know.
“We have to wait but it is far away from being perfect, of course.
"It is really hard for him and hard for us, but it is not to change.”
