LEWIN Nyatanga’s late goal broke Millwall’s hearts at The Den after Fred Onyedinma’s header with eight minutes left looked like it had rescued a point.
The Barnsley defender climbed at the back post to head past David Forde and give Lee Johnson’s side all three points.
It was cruel on the Lions but they only had themselves to blame after Alfie Mawson had also scored following a free-kick 11 minutes into the second half.
Millwall looked like the most likely winners after Onyedinma’s bullet header, but Barnsley were excellent throughout and probably just about deserved their win.
Onyedinma had earlier given the home side the lead before Sam Winnall equalised for Barnsley after 38 minutes, and the Lions winger probably deserved better than to end up on the losing side for the third game in a row.
Harris had said before the game that his players would have to learn quickly or he would make changes and he was true to his word as Sid Nelson and Shane Ferguson came into the back four.
Jimmy Abdou also made his comeback after injury and it certainly seemed to give the home side more control in midfield.
Still, there was an odd atmosphere in the ground in the opening stages and that was reflected on the pitch with some nervy play from the home side.
It wasn’t obvious that Harris was getting the response that he wanted from his side after Saturday’s defeat to Coventry until Onyedinma started to get into his stride.
And it was the winger who gave Millwall the lead on 27 minutes after Steve Morison had driven the ball across the six-yard line.
It looked as if Adam Davies had done enough to gather but with Onyedinma prone he was able to scoop the ball over the line with his second attempt.
That seemed to lift a cloud off Harris’ side and they really should have doubled their lead seven minutes later when Tony Craig’s header from Shaun Williams’ cross was helped over the line by Lee Gregory.
The Den was quickly silenced by a blast of referee Dean Whitestone’s whistle, however, as he deemed Gregory had fouled the keeper.
The added frustration was that it looked like Craig’s header was going to drift in anyway and a few minutes later that frustration was compounded as Johnson’s side found an equaliser.
Millwall had already been exposed down their left side with James Bree and Marley Watkins taking advantage of a narrow Millwall midfield to combine and cross a number of dangerous balls into the box.
And it was from the right that the goal came, Winnall turning in Watkins' cross-shot after an initial corner had been cleared.
Barnsley then went into the lead in the 56th minute when Mawson, who held talks with Millwall in the summer before joining the Tykes, found himself in space in the box after a free-kick to volley to the corner giving Forde no chance.
Harris brought on Aiden O’Brien and Ben Thompson to try to give his side more edge but it was Onyedinma who still looked the most threatening player on the pitch and he got his reward on 82 minutes when he headed in Ferguson’s corner.
But there was still time for late drama as Nyatanga powered a header past Forde in injury time.
