Egypt coach Hector Cuper decided not to risk his talisman despite telling reporters on Thursday that Salah had responded well to treatment on the shoulder injury he sustained in the Champions League final last month and was almost 100 percent certain to play in Egypt's first appearance at the finals for 28 years. Salah got injured during the finals of the Champions League while playing against Real Madrid after a tackle with Sergio Ramos in Kiev.
"Mo Salah is an important player for us, that is without a doubt", Cuper said.
In the second round in group A will play: Russia - Egypt (19 June) and Uruguay - Saudi Arabia (June 20).
After first matches in Group A, Russian Federation are leading this group as the World Cup hosts hammered Saudi Arabia 5-0 on Thursday.
But Cavani feels Uruguay deserved the win.
Salah will be on the spotlight when he takes to the field in Egypt's remaining Group A games.
The Barcelona player was making his first World Cup appearance since leaving Brazil in disgrace following his bite on Italy's Giorgio Chiellini but endured a frustrating afternoon.
The Pharaohs were issued a real scare when Cavani forced another world-class save from El Shenawy and hit the post in quick succession - going into the last ten minutes of the encounter. Marwan Mohsen as a lone striker is not likely to be enough for the team at this year's tournament. If he can prove his fitness before Egypt face Russian Federation next, nothing short of delivering a victory will be enough to keep his side's hopes of reaching the last 16 burning. We think it's unlikely that Salah will be risked in a game they are likely to lose anyway, especially when coming up against the mean defence of Godin and Gimenez.
Uruguay should provide their most hard test in the group stage, as they are packed with quality at both ends of the pitch.
Egypt, competing in a first World Cup since 1990, also expected to have midfielder Tarek Hamed available following a back problem.
Coach Oscar Tabarez says Suarez, 31, has learned from his past mistakes. "We've broken the spell". Cuper didn't use it as an excuse.
Spain open their World Cup campaign with what should be their toughest test in Group B. The Egyptian players are used to it. His involvement in today's match is in question.
