Immediately after the break, Jérémy Taravel was wearing the wrong tape around his ankles and asked to change it by the referee, while play continued.
Lokeren coach Peter Maes was furious with Taravel, but could smile again soon after as Ivan Leko lobbed the ball into the Anderlecht goal.
On the hour mark, Leko scored the equalizing goal, although Harbaoui had touched the ball with his hands during the play, without being noticed by the referee.
Anderlecht then again took control of the match and scored the 3-2 winner 15 minutes from the end through Guillaume Gillet, who shot the ball perfectly into the top corner of the goal.
Lokeren was unable to score thereafter, with Anderlecht coming close to a fourth goal as Mbokani hit the post.
