The Liverpool star took his tally to 22 goals for the Premier League season, but was then carried off at St James' Park after a blow to the head.
Liverpool have confirmed that the injury has ruled Salah out of Tuesday's UEFA Champions League semi-final, second leg against Barcelona.
But Jurgen Klopp says Salah will be fit to face Wolverhampton Wanderers on Sunday as Liverpool seek to claim a first Premier League title.
The chasing pack
Salah's closest rivals as he lookin the battle for the Golden Boot, presented by Cadbury, are Sergio Aguero, team-mate Sadio Mane and Pierre-Emerick Aubameyang, who scored his 20th goal against Brighton & Hove Albion on Sunday.
