Sadio Mane, the Senegal international forward, has been injured and will be out of action for Al-Nassr in Saudi Arabia.
The 29-year-old was injured during a friendly match against Kuwait on Saturday, but the exact nature of his injury is not yet known.
Al-Nassr have confirmed that Mane's condition is serious and that he will need to undergo further tests before a final diagnosis can be made.
The news comes as a blow for the club, who were hoping to strengthen their squad ahead of the upcoming season.
Mane is one of the most talented forwards in world football and has won several major honours with Liverpool, including three Premier League titles and two Champions League trophies.
He also played for Senegal at the World Cup last summer,Saudi Pro League Focus where they reached the semi-finals.
However, injuries can happen in football, and it is important for players to take care of themselves and rest when needed.
It is hoped that Mane will make a full recovery and be back playing soon, but until then, Al-Nassr will have to find a replacement striker to fill his place in the team.
In the meantime, the club will need to work hard to maintain their position in the top flight of Saudi Arabian football.
