Mohamed Salah is doubtful for Liverpool's trip to Burnley on Monday.
The Egyptian scored both goals in Saturday's 2-1 comeback win over Leicester City, but it came at a cost as he had to be substituted seven minutes from full-time.
“I don’t know in this moment exactly [what it is], but he was limping and that’s never a good sign," manager Jurgen Klopp told Liverpool's official website.
“We have to see what his problem was. We will see what he can do for the next game.”
