PSG stop ticket sales for away games
"Violence is at its height, we have reached a new level of urban guerrilla warfare," PSG chairman Robin Leproux said in a statement on the club's website on Tuesday.
"Until further notice, we shall not sell tickets to our supporters for our away games. It's a far-reaching and distressing decision but I have to ensure the safety of all."
The 38-year-old supporter, a member of the Kop of Boulogne, fell into a coma after being attacked by members of a rival group based in the Tribune d'Auteuil before Sunday's game.
Fans also clashed after the match, which PSG lost 3-0, and police said the seven people arrested and are still in custody.
PSG's long history of hooliganism peaked in November 2006 when a police officer shot and killed a member of the Boulogne Boys faction to protect an Israeli supporter under attack after a UEFA Cup match against Hapoel Tel Aviv.
Struggling PSG are 12th in the standings after a run of poor results has left them with 33 points from 26 games.
