It was feared that Salah could miss the entire tournament after he suffered a shoulder injury during last month's Champions League final in Kiev following a foul from Spanish defender Sergio Ramos.
Egypt goalkeeper Mohamed El-Shenawy had produced two fine saves to stop Luis Suarez and another from Edinson Cavani before he was beaten by Gimenez, but he was still optimistic of their chances in the group.
Egypt global goalkeeper Mohamed El-Shennawy has been named as man of the match following his exceptional performance against Uruguay.
"The decision is always taken by myself and the staff, especially in a case like Mo Salah's case, " Cuper said.
Booed by thousands of Egyptian fans from the start of the match, Suarez replied with a visible effort, only to lose the ball in promising situations.
"We think we are cursed, we are cursed", said Tabarez, who insisted that he hopes Egyptian talisman Salah will be fit after three weeks out injured with a shoulder problem.
Uruguay won but doubts about the team's attacking qualities remain.
"In good times, everything goes into the back of the net, while at other times the goal seems smaller". Marwan Mohsen as a lone striker is not likely to be enough for the team at this year's tournament.
Anything but a win against Saudi Arabia on Wednesday would be a surprise.
After arriving in Russian Federation for the tournament, Salah was not happy with an overeager fan who grabbed hold of his shoulder as he left the team coach and something similar happened as he made his way down the tunnel to take his place on the substitutes' bench on Friday.
The north Africans, contesting their first World Cup since 1990, were for the main part fairly comfortable in defence and Arsenal's Mohamed Elneny was a constant presence at the base of Egypt's midfield.
