World Cup winner Fabio Grosso, the Lyon coach, has suffered a head injury as the team bus came under attack from fans throwing projectiles before their French Ligue 1 match in Marseille., which was then called off.
The Lyon bus was hit on the way to Stade Velodrome, shattering some windows. Grosso was injured by falling shards of glass and needed medical treatment with his face heavily bleeding.
Lyon's Italian boss Fabio Grosso suffered a head injury when projectiles broke the bus window.
The match was subsequently called off before kick-off by French league officials.
Grosso scored the winning penalty kick for Italy in the shoot-out victory over France in the 2006 World Cup final.
Both clubs have been under pressure lately.
Despite replacing Marcelino with Gennaro Gattuso as coach in September, Marseille have still been showing poor form with one win and three losses in their last four league games.
Lyon are the only team still winless in the league, and replacing Laurent Blanc with Grosso as coach in September hasn't yet paid off for Lyon, who remain in last place.
