Nantes moved within four points of opponents Bordeaux in the Ligue 1 table after a remarkable and fortuitous 2-1 win at the Stade de la Beaujoire.
Bordeaux struck a post and had three efforts cleared off the line, in addition to losing the game to a freak own goal from their keeper Azbe Jug.
Jordan Veretout had earlier opened the scoring for Nantes while Bordeaux's equaliser was another own goal, Kian Hansen the unlucky Nantes player.
Yoann Touzghar snatched a valuable point for strugglers Lens as they were involved in a six-goal thriller at Montpellier.
Morgan Sanson and Lucas Barrios gave the hosts a 2-0 lead inside 16 minutes, but Lens hit back through Perrick Valdivia and Baptiste Guillaume.
Anthony Mounier made it 3-2 to Montpellier in the 62nd minute but it was not enough to seal the win as Touzghar took advantage of a goalkeeping error by Laurent Pionnier to claim the draw which moved 19th place Lens to within two points of safety.
Bastia scored late in each half to beat 10-man Rennes 2-0 and end a three-match losing run.
Ryad Boudebouz brilliantly opened the scoring in first-half stoppage time and Yannick Cahuzac clinched the points in the 81st minute with his first Ligue 1 goal. Rennes had earlier lost Fallou Diagne to a straight red card in the 26th minute.
The result lifted Bastia above Lens in the table, though they remain in the relegation zone. Rennes are sixth, four points outside the European places.
Reims scored twice in the last 12 minutes to snatch a 3-2 comeback victory over 10-man Evian at the Stade Auguste Delaune II.
The hosts took a 14th-minute lead through Diego, but Evian hit back with second-half goals from Daniel Wass and Cedric Cambon to set up the chance for a fourth Ligue 1 win in five games.
However, the game turned on its head during a two-minute spell which saw Reims defender Aissa Mandi level things up at 2-2, Evian lose Cambon to a red card and then Diego net the winning goal.
Reims' victory comes after successive league defeats to Guingamp and Lyon and keeps them in the top 10, while Evian are now just two points above the relegation zone.
Lorient moved clear of the bottom three as a dominant first-half display earned them a 3-1 win at home to Metz.
The hosts raced into a 3-0 lead before half-time as goals from Jordan Ayew, Raphael Guerreiro and Benjamin Jeannot put them in charge.
Yeni Ngbakoto pulled a goal back a minute into the second half, but the visitors had left themselves with too much to do.
The win sent Lorient up to 13th in Ligue 1, three points above the bottom three and one ahead of their opponents.
