Liverpool manager Jurgen Klopp has claimed that he will not learn the extent of Philippe Coutinho's injury until a scan has been performed.
The Brazilian playmaker was stretchered off the pitch with a brace on his ankle around the half-hour mark of the Reds' 2-0 victory over Sunderland at Anfield this afternoon.
The 24-year-old, who has scored six goals in all competitions this season, winced in pain after he and Didier Ndong caught one another's feet in the penalty area.
After the match, Klopp told BBC Sport: "[Coutinho's injury] is an ankle injury but we can't say anymore until we see a scan. [Roberto] Firmino got a knock on the calf as well. That should not be that serious."
On the game itself, Klopp said: "I was not in doubt about the result. I just tried to fix a few things like using space better. It was an intense game for us and a deserved win at the end.
"The excitement is in the detail and that means you have to celebrate before you score a goal and push the team on if possible. It worked out. It is important the crowd know about the importance of their support.
"There is a lot to analyse. This was the most defensive team I ever saw in my life. Sunderland always play a defensive style and that is OK. We forced them to be that. It is the most difficult thing in world football to come through but we stayed concentrated, worked for the moment and found a way."
Liverpool have moved back to the top of the Premier League table for the time being.
