The Liverpool star was challenged by Dani Alves early on in the game and was seen in discomfort.
According to the Express, an LFC TV commentator exclaimed after the incident: "Concern for Sadio Mane there. Just got a bang."
Mane was able to continue, playing the entire 90 minutes, winning a penalty for Aliou Cisse's side towards the end of the first half which Famara Diedhiou converted, as the game ended 1-1.
Mane's ability to finish the match will come as a sigh of relief for Jurgen Klopp who is sweating over Mohamed Salah's fitness, in time for next weekend's crunch clash with Manchester United at Old Trafford.
