Liverpool defender Dejan Lovren is expected to be back in full training next week when his team-mates return from their warm-weather training camp in Spain.
Midfielder Marko Grujic, who has not featured because of a hamstring injury, also stayed behind at the club's Melwood training ground.
"That was the decision of the medical department," boss Jurgen Klopp told Liverpoolfc.com, when asked why the likes of Lovren and Grujic were left at home.
"Of course we have here exactly the same possibilities in the medical department and we have fantastic people at home and they can take care of the players, which makes more sense.
"Hopefully, especially Dejan, (they) can come back to training after when we come back on Sunday, that would be great.
"Same for Marko Grujic, who is close but not close enough to make the sessions with us, and it's not nice for a player when you're close but you see this."
