Liverpool talisman Mohamed Salah hobbled off after getting injured in his side's 2-1 win over Leicester City in a crunch Premier League clash at Anfield.
Salah was downed by Leicester's Hamza Choudhury after a strong challenge.

Liverpool are awaiting the news on Salah.
Liverpool have a two-week off until they resume play with the international duty on offer.
However, when they return to action, Liverpool take on Manchester United before hosting Tottenham Hotspur and then facing Arsenal in the Carabao Cup fourth round.
Manager Klopp didn't like what he saw and lashed out at the Leicester player.
He said he cannot get over the Choudhury yellow card.
"Mo is lying in the dressing room. How can he be okay? We don't know how he is, but that's hard. Three years in a row, we've been the team with the lowest yellow cards, we don't do these things. But that's really not okay," said an angry Klopp after the match.
"How did he only get a yellow card? Mo limped off."
Meanwhile, Choudhury was subjected to racial abuse by some Liverpool fans after his tackle on Salah.
"We are appalled by these comments, which the club has reported to the police and to the social media platform on which they were made," a Leicester spokesperson said.
"Discriminatory behavior has no place in football or in society and we will seek the strongest possible course of action."
