Previews: Security tightened for PSG match

PARIS - Brief news ahead of this weekend's matches in Ligue 1:

Security has been beefed up for Paris Saint-Germain's home match against Sochaux on Saturday with 1,000 police to be on duty.

The game will be PSG's first at Parc des Princes since a fan suffered life-threatening injuries in a fight between rival Paris supporters before a match against Olympique Marseille on February 28.

The 38-year-old has been in a coma since.

Champions Girondins Bordeaux will be without defender Marc Planus because of damaged knee ligaments when they visit Monaco on Saturday. Midfielder and captain Alou Diarra is a doubt to start due to a sore left thigh.

Monaco will be missing defender Djimi Traore (suspended) and South Korea forward Park Chu-young (thigh).

Strugglers Boulogne, visiting Nancy on Saturday, are without defender Yoann Lachor, who has been suspended for five matches for fighting with Olympique Lyon striker Bafetimbi Gomis last weekend.

Lachor then insulted the referee after receiving a red card. Boulogne held Lyon to a goalless draw.

Third-placed Auxerre will be without Swiss defender Stephane Grichting because of a foot injury when they visit second-placed Montpellier in one of the highlights of the weekend programme on Saturday.

Strugglers Nice, visiting Le Mans on Saturday, have started proceedings to sack coach Didier Olle-Nicolle.

Eric Roy, Rene Marsiglia and Frederic Gioria, all part of the club's staff, will share the coaching duties for the match at Le Mans on Saturday.
