Newcastle's Alexander Isak scored a dramatic stoppage-time winner at Nottingham Forest from the penalty spot to keep their hopes of a top-four finish firmly alive.
Isak, who had earlier cancelled out Emmanuel Dennis' opener in the first half, coolly placed his spot-kick into the right corner after Moussa Niakhate was penalised for handball in the box.
In an eventful encounter, Newcastle substitute Elliot Anderson thought he had made it 2-1 when he thumped in a header at the back post, only for it to be ruled out by VAR for offside in the build-up.
Newcastle were on top for large spells and hit the crossbar twice in the first half, either side of a glorious chance fired over by Joe Willock from close range.
