Curtis Jones and Naby Keita did not feature against Strasbourg as Liverpool suffered a 3-0 defeat.
Ibou Konate played from the start but left the pitch in the 57th minute after a collision with a Strasbourg player.
Jurgen Klopp has shared an update on these three players.
"Naby is ill and Curtis felt a little bit and we couldn't take any risks. All of a sudden the team was really young and we play [against] a really strong Strasbourg side," he told Liverpool's media team.
"We don't know exactly yet on Ibou, but it doesn't look too concerning, so I hope we caught it in the right moment.”
"Naby is ill, so no," Klopp said when asked if Keita and Jones could feature against Fulham. "Curtis, we have to see.
"[There] was no impact or whatever, so that always makes it a bit, 'My god, what could it be?'
“We had no time; he felt it today and he wanted to play desperately, but then the medical department said no and that we needed to make further tests. We will do that tomorrow and then we will know more."
