London - A rare goal by Martin Kelly earned Crystal Palace a 1-0 win away to Tottenham Hotspur on Sunday and a place in the FA Cup quarter-finals.
The South Londoners are now hoping to reach their first FA Cup final since 1990, when they were beaten by Manchester United in a replay.
Kelly's goal -- his first since netting for Liverpool at Chelsea in November 2011 -- also ended Tottenham's hopes of a league and domestic cup double.
Maurico Pochettino's side are currently second in the Premier League but whatever happens now they will not be emulating Spurs' celebrated Double-winning squad of 1961.
Palace manager Alan Pardew will be hoping it can be third time lucky for him in the FA Cup as he played for Palace in the 1990 final and was the West Ham manager when they lost to Liverpool in the 2006 showpiece match.
The White Hart Lane return of former Tottenham man Emmanuel Adebayor turned out to be disappointing.
The Togo striker, having sauntered out behind his Palace team-mates, was booed by many home fans before kick-off and throughout the game but did not look like scoring.
North London side Tottenham almost scored in the third minute when Dele Alli's header at the back post from a corner was blocked on the line by Yohan Cabaye and Josh Onomah nodded the rebound over.
Palace felt they should have had a penalty when Jordan Mutch's volley hit Nabil Bentaleb on an arm but referee Craig Pawson disagreed.
Kyle Walker and then Adebayor were hurt as tackles began to fly in from both sides. Both men recovered with Walker then sending a header over Michel Vorm, his own goalkeeper, who was just able to claw it away before it crossed the line.
The free-kick count continued to mount, with Palace conceding most of them.
The visitors almost took the lead when Scott Dann took down a high ball and played Joe Ledley in but Vorm dived bravely at the Welshman's feet to save.
Spurs' reply was another near miss from Alli, who saw his low shot hit the far post, rebound across the goal on to the other upright and be cleared before a team-mate could pounce.
Onomah flashed a snapshot across goal but Spurs continued to look vulnerable at the other end. A chance finally came Adebayor's way but Eric Dier was across swiftly to block.
Palace goalkeeper Wayne Hennessey had to make a diving save to keep out Harry Kane's long-range free-kick and the visitors took the lead in stoppage-time through Kelly.
Wilfried Zaha teed up the defender on the right of the box and his drive was too powerful for Vorm at his near post.
Spurs replaced Mousa Dembele with Christian Eriksen at the break and it wasn't long before Hennessey had to dive to deny Kane once more.
It then needed Kelly's intervention on the line to stop Onomah converting Kane's flick across goal.
Alli, having barged Cabaye into advertising hoardings to send tempers flaring again, fired just wide from 25 yards as Spurs pressed for an equaliser. Eriksen was next to have a go but Hennessey saved.
Cabaye was booked for tripping Danny Rose before Palace sent on fit-again winger Yannick Bolasie in place of Adebayor, who had only occasionally been in the game.
Connor Wickham went on a dangerous run that saw his shot blocked as Palace pressed for a clinching second goal.
Wickham did convert Bolasie's cross with four minutes remaining but the goal was ruled out for offside.
Kane saw a header blocked by a scrum of Palace bodies in front of their goal seconds before referee Pawson blew for time.
