Newcastle United were denied a valuable win at Wolves as Willy Boly forced a 1-1 draw in the final few seconds at Molineux.
Isaac Hayden looked to have secured three important points for the visitors in their fight for Premier League survival, only for Boly's header to deny them a third win in four league matches in the fifth minute of injury time.
Rafael Benitez cut a furious figure on the touchline, with the equaliser coming close to a minute after the allotted time added on had expired.
Raul Jimenez fired over from a decent position, having earlier seen penalty shouts waved away following a Christian Atsu challenge, as Wolves provided all the early attacking endeavour.
Martin Dubravka made a good save to deny Jimenez a goal before the break, the striker having cut into the area from the left and fired in a shot that deflected off Fabian Schar.
Salomon Rondon was Newcastle's biggest threat and he spurned a good chance for a goal moments before half-time, slicing his shot high and wide via a slight deflection after working space in the box.
Matt Doherty somehow failed to convert with the goal gaping following a corner and Newcastle punished the miss 56 minutes in when Hayden's strike from just inside the right of the area was palmed into his own net by Patricio.
Benitez handed a debut to club-record signing Miguel Almiron off the bench but he had little opportunity to impress as Newcastle attempted to hold on to their lead.
They thought they had until the final few seconds of injury time, when Adama Traore's cross looped towards the far post from the right and Dubravka failed to collect, allowing the leaping Boly to head home.
What does it mean? Newcastle denied big step towards safety
The result moves the Magpies a point above the bottom three, but to miss out on a victory in such fashion will feel like a defeat for Benitez and his players.
Survival is still in their hands, but their meeting with bottom-of-the-table Huddersfield Town in their next match is looking like a potentially pivotal one.
Wolves stay seventh, two points above Watford and 11 behind sixth-place Chelsea.
Not content with another commanding defensive performance, Schar earned himself an assist for Hayden's goal. He really has taken to the Premier League this season.
Keepers strike a calamitous balance
Dubravka's mistake was costly, but Patricio's error looked worse. Perhaps he was simply caught cold having had so little to do until that point.
Wolves head to Bristol City in the FA Cup on Sunday before they face Bournemouth in the league on February 23. Newcastle do not play again until that date, when they host Huddersfield.
