The Dutch captain was substituted midway through the Reds’ defeat to Brentford.
Virgil van Dijk of Liverpool will see a specialist about his hamstring injury as the club waits to see if he will be out for an extended period of time.
Jurgen Klopp made three substitutions at halftime against Brentford, with the Reds trailing by two goals at the time.
However, Van Dijk’s departure was the result of a fitness concern, which Jurgen Klopp described as a precautionary move because the No.4 was willing to play on.
However, there are concerns that his injury is more serious than first thought, and Liverpool may face defining games in their quest for a top-four finish without the £75 million man.
Liverpool, who are sixth in the Premier League table after a wildly inconsistent season, have struggled defensively this season, and injuries have been a major issue all season.
