Local football fans have been ordered to stay away from Sunday's high-profile African Nations Cup quarter-final clash between Morocco and Algeria because there is no room for them.
With around 15,000 to 20,000 Algerian supporters expected to make the short trip across the border for the north African derby, organising committee member Ben Amar Hamed has told locals hoping to get into the Taeib M'hiri stadium to stay away.
The ground only holds 22,000 people and the stadium will be packed to the rafters just as every Algeria match was when the team played their group games in Sousse.
As a result, organisers are worried about the security implications.
After the team's win over Egypt in the first round, the Algerian Football Federation was hit with a 5,000-dollar fine because of their fans' behaviour which included throwing missiles onto the pitch.
One even landed in the VIP area.
"This is why I am asking the people of Sfax to stay away from the stadium and leave the place open for foreigners. I know it will be disappointing for them," said Hamed.
Meanwhile, Sfax governer Mohamed Tounsi was meeting local police chiefs to discuss the security situation for another game which, like the clash between Algeria and Egypt, will be classed high-risk.
