Belgium international Lois Openda scored a late equaliser as 10-man Lens drew 1-1 at Reims on Sunday to remain unbeaten in Ligue 1 this season.
Arsenal loanee Folarin Balogun struck his fifth goal in six games to put Reims ahead shortly after Deiver Machado's red card midway through the second half.
Openda netted for the fourth match running to earn Franck Haise's side a point, although they dropped two behind Paris Saint-Germain and Marseille at the top.
"We can be satisfied we didn't accept defeat with 10 men, because that's now 14 matches without losing going back to last season," said Haise.
"That means we have a lot of character."
