Liverpool head coach Arne Slot says Jeremie Frimpong will miss "a few weeks" with a groin injury - a better outcome than the club had feared.
The versatile defender had to be substituted after four minutes of the 6-0 win over Qarabag on Wednesday.
The injury means the Reds have no recognised right-backs available to face Newcastle United in the Premier League on Saturday.
"He [Frimpong] will definitely not be in the squad tomorrow," Slot said.
"He is out for a few weeks, but [it's] not as bad as we thought, so something positive from something not so positive.
