In a group comprising hosts Russia, Saudi Arabia and Uruguay, arguably the weakest group in the tournament, hopes are high in Egypt that progression is a realistic possibility.
If Egypt make it out of Group A in second place, which shouldn't be too much to ask, they will likely come up against Spain in the round of 16.
Egypt coach Hector Cuper confirmed the news suggesting that Salah could emerge as one of the tournament's most prolific goalscorers.
"If we see at the last minute that there is an issue then we will see if it can be resolved, but certainly he does not feel afraid".
He added: "I don't really know [if Salah is going to play], because he made the recovery in England in secrecy".
Cuper said officials would continue to monitor Salah during their training session Thursday.

Of those wounded, 92 were hit by live fire while the rest suffered from tear gas inhalation, the news agency said. The Israeli army said that it had repelled around 10,000 Palestinians who converged on five points of the border.
Mido - who scored 20 goals in 51 games for Egypt - is hopeful that Salah will be ready to go for the showpiece event.
"I can nearly assure you 100 percent he'll play", Cuper said in the pre-match press conference.
"He could become the top goalscorer here and one of the greatest players". I don't think anyone has bad will or tries to deliberately injure a player.
Whether he plays or not, there is no doubting the commitment of the Egypt fans who have travelled from around the world to Yekaterinburg, 1,760 km (1,100 miles) east of Moscow.
Thousands of supporters turned up to watch Egypt's final, late night training session before taking flight for Russian Federation, cheering wildly.
Salah is regarded as a contender for the Ballon d'Or, alongside Argentina's Lionel Messi, Portugal's Cristiano Ronaldo and Neymar of Brazil.
