Huddersfield lost seven consecutive home games
Steve Mounie scored a goal in the 91st minute against the Wolves to end Huddersfield's 14-win win streak and give Jan Siewert his first win as Terriers manager.
Mounie bounced back inside the six-yard area after Karlan Grant's shot was blocked to give Town a deserved three-point merit and spark full-time crazy celebrations.
The striker was assaulted by his teammates after scoring, while Siewert was overwhelmed by his staff in the back shop and as players tied their arms to celebrate in front of their fans.
Huddersfield remains at the bottom of the table, still at 11 points of safety, but wins his first victory since the victory over Wolves at Molineux on November 25th.
It seemed like another defeat in front of the goal would be expensive for the Terriers, while Mounie put a header in the side net at close range earlier in the second half.
He also opened a narrow pass near the post while Jonathan Hogg and Jon Gorenc Stankovic could have done better with their lead after halftime.
Woeful Wolves missed the chance to finish seventh and saw the end of his eight-game unbeaten streak.
The only real chances for these players were to get into the first half when Raul Jimenez took a look at the head and Matt Doherty scratched a shot from the far post.
Great celebrations for a rare victory
Mounie's goal was his second of the season
Huddersfield's gloomy situation at the bottom of the table means that this victory will probably be futile in terms of survival in the Premier League, but the emotional scenes showed how the three points mattered to Siewert, the players and the fans.
Siewert's four previous games ended in defeats against Everton, Chelsea, Arsenal and Newcastle, and after that, the German has strongly criticized his players, calling for more fighting.
He made eight changes to play the Wolves, including recalling Mounie and giving fellow striker Karlan Grant a first start for the club, and players responded to the call.
Huddersfield started with a high intensity, preventing the Wolves from gaining a foothold in the match and, in the second half, the hosts dominated, creating the only real chances.
The only part of their performance that was missing was Huddersfield's finish in front of goal, a familiar theme of the season for the league's top scorers, both under the colors of Siewert and his former coach David Wagner.
Mounie had been as guilty as any of his teammates, but when the ball fell on him while he was on the ground in the penalty area, he managed to finish the finish.
It remains to be seen if the three points can give a boost of survival with 10 games to play.
