Liverpool suffered a blow on Thursday when Sadio Mane was substituted with an injury against Wolves.
The 27-year-old winger was taken off 30 minutes into the Premier League clash at Molineux Stadium after picking up a knock.
The Senegal international went down twice in quick succession and was treated on the field but then walked down the tunnel and was replaced by January signing Takumi Minamino.
Mane immediately signalled to the Liverpool bench that he needed to come off and he was replaced soon after by recent arrival Takumi Minamino.
It was unclear what the problem was with Mane, although it appeared to be muscular as he made his way down the tunnel.
Any long-term problem for Mane would be a blow to Jurgen Klopp, the forward having scored 11 and assisted a further six goals in the league this season.
