Jurgen Klopp has revealed Sadio Mane suffered a dead leg and knee injury in Sunday's 2-1 over Chelsea.
The Senegalese was forced off after N'Golo Kante's mazy run and finish got Chelsea back in the game.
"It was a knock on the bone, around the knee, and a dead leg," said Klopp. "That's an awful combination.
"He tried everything. I think you saw there was one counter situation when he really tried and I would say on a non-dead-leg day he will get that ball, but no chance.
"Then we say, 'come on, now we have to do it' and changed. That's it."
