Darouèche's next major competition was the 2014 African Championships in Athletics. He was disqualified from the 400 metres hurdles due to violating IAAF rule 168.7(a) which states an athlete shall be disqualified if his foot or leg is, at the instant of clearance, beside the hurdle (on either side) or below the horizontal plane of the top of the hurdle. The 2015 World Championships in Athletics was Darouèche's second World Championships. He recorded the slowest time out of any athlete in the heat round of the 400 metres hurdles with a time of 53.06 seconds. At the 2016 Summer Olympics, Darouèche competed in the 400 metres hurdles. Darouèche was drawn in heat two, a heat containing eventual bronze medalist Yasmani Copello. In the race on 15 August 2016, Darouèche ran a time of 52.32 seconds. Darouèche's time was the 45th-quickest out of 46 finishers with only Bahamian Jeffery Gibson slower. Darouèche's time was 2.55 seconds slower than the slowest athlete to progress to the nest round and, therefore, he was eliminated.
