Celtic came from behind to snatch a thrilling Scottish Premiership victory over 10-man Motherwell to keep the pressure on league leaders Hearts.
Tomas Cvancara's penalty and Hyun-jun Yang's settler proved crucial in the second half for the title-chasing hosts, with Hearts going to Kilmarnock later on Saturday and third-placed Rangers away to St Mirren on Sunday.
Elijah Just had put the impressive visitors ahead before Yang punished a defensive blunder, akin to the one that undid Jens Berthel Askou's side on their last visit to this stadium.
Cvancara converted after Emmanuel Longelo was punished for holding in the area, the wing back was then ordered off after video assistant referee (VAR) intervened.
Yang sealed a vital victory that potentially ends Motherwell's title chances but provided a huge boost to Celtic's with just eight games remaining for the defending champions.
This contest had thriller written all over it before kick-off. It delivered and then some.
The visitors looked impressive but looked to have fallen behind when Alex Oxlade-Chamberlain's fierce drive was touched on to the post by Calum Ward, the ball squirmed along the line but not over - just.
On chances, Celtic were ahead. On almost every other measure, Motherwell were and got their reward.
Reo Hatate dithered inexplicably on the edge of his own box when isolated. He was caught, the ball fell to Just and he smashed home into the corner to send a sell-out away end into raptures.
The response was swift but gift-wrapped by their opponents.
Yang pounced after Tom Sparrow misplaced a pass in his own box. Benjamin Nygren got there, cut back, Ward parried but it fell perfectly for the South Korean and he smashed home.
Berthel-Askou's side didn't flinch, retaining their composure as the teams traded chances with Nygren striking a post.
The noise levels then went through the roof when Ward misjudged a corner, Longelo misjudged his positioning and he, eventually, was deemed to have held Daizen Maeda.
A penalty, a red card and a goal followed, with Yang adding a third to seal a crucial win in this thrilling title fight.
