Sky Italia footage showed damage to two bus windows and Grosso being led into the stadium by two assistants. He was covering his face with his hands, which were stained with blood.

Italian media said Grosso suffered injuries to his scalp and face.

"He can't hold a conversation, he had shards of glass in his face," Lyon's club president, John Textor added.

"I'm very angry - our players, our coach, prepared for tonight and the fans wanted to see the game played," he told Prime Video.

Fans were asked to leave the stadium calmly.

"Following the injuries of Lyon members, considering the opinion of the club, which did not wish to start the match, and the established protocol, the decision was taken not to play the match," said referee Francois Letexier, quoted by French media.

"The images of the OL bus attacked with stones and its supporters, and of Fabio Grosso's blooded face, are appalling," French sports minister said on social media platform X, formerly known as Twitter.

"These unacceptable acts deny the very values of soccer and sport, and the perpetrators must all be found and severely punished," she added.

Seven suspects had been arrested on Sunday night, the minister added.

Marseille said it accepted the decision taken by the French Professional League to call off the game, pledging to make sure it could "take place at the Stade Velodrome as soon as possible and under the best possible conditions".
