Bordeaux down Montpellier
It was Bordeaux's second win in three games and moved it up to 13th place, while Montpellier is 15th.
Montpellier was up against it after Yassine Jebbour was shown a straight red card in the 18th minute for a dangerous high tackle on fellow defender Lucas Orban.
But the home side labored to make the most of the extra man and had to wait until the 76th to take the lead when Diabate converted Nicolas Maurice-Belay's cross from the left.
Obraniak sealed the win with a solo goal in injury time, finishing confidently after he collected the ball in midfield and sprinted into the penalty area.
