Tunisia striker Issam Jomaa has been forced to withdraw from his country's World Cup squad because of a knee injury.

The 22-year-old will be replaced by Bastia star Chouki Ben Saada who won the under-17 World Championship with France in 2001 before switching his allegiance to Tunisia.

Jomaa was not expected to be in Tunisia's starting line-up for their opening Group H clash against Saudi Arabia on June 14.

The Lens forward is famed for his crosses and sudden bursts of acceleration down the left wing and had been expected to be used as a substitute in this month's tournament if Tunisia needed to make a sudden impact in Germany.
