Salah's early exit from the Champions League final.
According to information released after a medical examination following the final, the Egyptian suffered a clavicle acromion subluxation, which means Salah could be out for a minimum of three weeks.
Salah was withdrawn on the 31-minute mark in the 3-1 loss after he fell on his shoulder following a tussle with Los Blancos captain Sergio Ramos.
The nature of Salah's injury is still unclear but Egypt's medical team are confident he will be available for the World Cup in Russian Federation.
Fears quickly turned from Ukraine to Russian Federation as it was believed the Egyptian worldwide would miss the World Cup, but the forward has since revealed he is optimistic of featuring for his national team in the prestigious tournament.More news: Positive signs suggest Mohamed Salah will return for World Cup

The 25-year-old sustained the problem when he was dragged awkwardly to the turf following a challenge with Sergio Ramos, leading some to claim the Madrid defender had deliberately tried to injure Liverpool's star forward.
Do you think Salah will be ready for the World Cup?
The match was goalless but Jurgen Klopp's side were in the ascendency until midway through the first half when they lost their 44-goal forward with a shoulder injury after falling in a tangle with Sergio Ramos.
All the same, his ongoing behaviour is not very sporting and it was particularly disappointing to see it affect Salah, whose transformation into a Ballon d'Or contender has been one of the feelgood fairytales of the season.
Salah was replaced by Adam Lallana, who had only recently returned from a hamstring injury.
The Spanish global brought down Mo Salah in the first half, resulting in the Egyptian suffering a dislocated shoulder and missing the rest of the 90 minutes.
