article: Hearts dominated the first half, Jamie Walker scoring a third-minute penalty after Kevin Gomis brought him down. Callum Paterson headed home Don Cowie's free-kick early on the resumption. But Dundee captain Darren O'Dea drilled home to cut the deficit, Paul McGowan smashed home the equaliser before Paterson headed into his own net. Victory, their fourth in eight games, lifted the Dark Blues into seventh place, while fourth-placed Hearts are now without a win in four. Winger Walker has been the subject of much discussion this season with his twisting runs regularly inducing defenders into rash challenges inside the box. And once again he earned his team a penalty after being played in by Bjorn Johnsen. The 23-year-old picked himself up to send Scott Bain the wrong way for his fifth successful spot-kick, and eighth goal, of the season. Walker was ably assisted by Paterson, who Hearts director of football Craig Levein said earlier this week will not be leaving the club in January unless they receive a seven-figure offer. When the Scotland full-back headed home Don Cowie's free-kick three minutes into the second period, his eighth goal of the season and 37th for the club overall, the visitors looked destined for all three points. The home fans made their frustrations known as a fifth home defeat of the season loomed. Manager Paul Hartley responded by replacing midfielder Mark O'Hara with Paul McGowan, and the momentum of the game changed. O'Dea pulled one back with a rare right-foot strike after the Hearts defence failed to clear the ball from their own box. With confidence visibly growing, McGowan latched onto a ball from Craig Wighton and clipped the ball over the advancing Jack Hamilton to draw Dundee level. A neck injury to Hearts midfielder Don Cowie, who was stretchered off after a delay of seven minutes and taken to hospital, appeared to adversely affect the visitors. The 1400 Hearts fans who made the trip to Dundee could barely believe their team's collapse when the hosts completed their comeback in the 93rd minute, Haber getting up to meet a Tom Hateley free-kick from close range, only for Hearts defender Paterson to direct a header into his own net. Hearts should have been out of sight at half time. Paterson, Walker, Arnaud Djoum and Krystian Novak all came close to adding further goals to Walker's opener, and Cathro must wonder what his players have to do to get that first win of his tenure. They have two more opportunities in the next week before the winter break, with Kilmarnock - on Tuesday - and Aberdeen - next Friday - both visiting Tynecastle. Dundee boss Paul Hartley: "The first half we were really poor, the game could have been dead and buried. That's the worst we have been for a long time. "The second half we showed a real grit, determination and desire to stay in the game at 2-0 down and we always thought we would get chances. Once we got the goal back to make it 2-1 we could feel momentum building. "I'm really proud
summary: Dundee came from two goals down to stun Hearts with an injury-time winner and leave Ian Cathro still waiting for his first win as head coach.
