The Liverpool midfielder appeared to be injured in a pre-match training session.
The paper say that Keita had to exit the squad's pre-match open training session in Istanbul on Tuesday night, looking in some discomfort as he headed up the tunnel.
He's now due to be assessed ahead of the fixture.
It's just the latest potential injury setback for the 24-year-old since making the switch from RB Leipzig to Anfield.
He had a number of small issues throughout 2018/19, struggling to get up to full match fitness and make an impact in the Liverpool side. He made just 16 starts in the Premier League.
His season eventually ended early after an abductor injury that ruled him out of an important May.
Recently he has looked sharp coming off the bench, especially in the Community Shield match against Manchester City, but after a disrupted pre-season this latest problem threatens to further delay becoming a prime pick in heart of Klopp's midfield.
It's fair to say that some Liverpool fans are frustrated with the situation, hoping that the Guinean international can be more robust and physically ready for the challenges ahead this term.

Naby Keïta is testing my patience these days with his injury problems. Availability supersedes ability, it's getting Lallana level ridiculous now. Fuming.— RF9 (@SambaRole) August 13, 2019
If it carries on we need to offload next summer. Love the lad but we can’t be dealing with this all the time.— Blxnd (@fruuiity3) August 13, 2019

Dont worry we have the squad depth to cope with injuries, that's why we didn't bother to sign anybody to make the squad stronger,— Klopp on (@Kopitekav) August 13, 2019
