Only four of the 10 Ligue 1 matches scheduled for this weekend took place, with the other six postponed due to protests against increases in fuel tax and rising living costs.
Saturday's match between league leaders Paris St Germain and third-place Montpellier was one of the casualties, as was Friday's south-coast derby between Monaco and Nice.
That opened the way for second-place Lille to put some distance between themselves and the teams behind them but it took a penalty from Pepe, his sixth from the spot this season, to get them a point.

But Pepe got his 11th goal of the season deep into injury time to level the score.
It was a cruel blow to Reims, who had hardly put a foot wrong against the higher-placed club.
In the day's only other game, visitors Caen trailed Strasbourg twice but came back both times to secure a 2-2 draw.
The result lifted Strasbourg into eighth, while Caen, who have not won in 10 league games, moved a point clear of second-from-bottom club Monaco, who have a game in hand.
