Lorient remain firmly involved in the Ligue 1 relegation battle after they suffered a disappointing home defeat to Evian TG.
Brice Dja Djedje struck the only goal of the game in the 19th minute.
Yannick Sango found space on the right and whipped in a cross that deceived Lorient goalkeeper Fabien Audard and left the Ivorian to tap into the unguarded goal.
Evian remained disciplined at the back and restricted their opponents to speculative long-range efforts.
Arnold Mvuemba fizzed just over with a free kick for the hosts, before Evian's Aldo Angoula saw his powerful header well saved by Audard.
Seber Khelifa almost doubled the visitors' lead late on, but his low shot was tipped around the post by man of the match Audard.
