Lens forward Toifilou Maoulida struck a second-half equaliser to deny already-relegated Grenoble what would have been only their second away win in Ligue 1 this evening.
Maoulida restored parity midway through the second period after Laurent Courtois had put the visitors ahead on the stroke of half-time, leaving Courtois to regret passing up the chance to put his side two up from the penalty spot.
With Grenoble already consigned to the drop and the hosts comfortable in mid-table there was little other than pride at stake at the Stade Felix Bollaert.
GF38 nonetheless started brightly and almost went ahead as early as the seventh minute when Josip Tadic raced onto a long ball and found himself one on one with Hamdi Kasraoui, but the Lens goalkeeper came out on top.
The home team went close to a breakthrough of their own after 24 minutes when Sebastien Roudet's corner was met by Romain Sartre, but his header was deflected over the bar.
Le Sang et Or were again unfortunate not to go ahead in the 44th minute, Marco Ramos' blast flying just wide of Jody Viviani's goal.
And moments later Lens were behind.
Nenad Kovacevic lost possession in midfield, allowing Courtois to seize on the ball and burst forward before lashing in a 25-yard shot which took a wicked deflection and looped over Kasraoui.
Kasraoui kept his side in the game seven minutes after the break when he saved a poor penalty by Courtois, awarded after Tadic was brought down by Alaeddine Yahia.
And, 15 minutes later, the visitors were made to pay for that miss when Maoulida rose highest and directed his header from Yohan Demont's corner past Viviani.
Lens could have won it 18 minutes from time when Ramos tried his luck with a fierce effort from 25 yards, but the ball flew just wide.
