The Wigan Athletic striker, who scored the Pharaohs' only goal, sustained the problem during the second half of the game.

He had to stay on the field until the final whistle as Egypt's three substitutions were already made.

The news will come as a blow to Wigan coach Steve Bruce, who will have to do without the team's top scorer in the Premiership games against Everton and Arsenal.

Zaki, who is on loan from Zamalek, scored ten league goals for the Latics so far this season.

Bruce is expected to rely on Zaki's compatriot Mido and Colombian striker Hugo Rodallega in the next two games.
