United States forward Timothy Weah ended a seven-week layoff entering in the 68th minute of the game. Weah had not played in a match since Dec. 1 at Rennes. Two days later, he injured a thigh during training.
The result lifted Jocelyn Gourvennec's side, who lost three of their six first games this season, up to eighth on 32 points from 21 games, 18 behind leaders Paris Saint-Germain and seven adrift of second-placed Nice.
Lille made a brilliant start in a game that had been postponed because of COVID-19 cases at Lorient, breaking the deadlock in the 10th minute when Lihadji fired home from close range after Paul Nardi parried Jonathan David's strike.
