Luton Town made a mockery of the 85 places between themselves and Norwich City to become the first minor league club to beat a top-flight side in the FA Cup for 24 years on Saturday.
Scott Rendell scored 10 minutes from time to earn the fifth-tier side a 1-0 win at Norwich's Carrow Road stadium and leave another indelible mark in the competition's giant-killing history.
Premier League Queens Park Rangers also suffered a humiliating 4-2 exit at the hands of third tier Milton Keynes Dons to pile on the misery for the struggling London club who are mired deep in a relegation battle.
Not since Sutton United beat Coventry City in the third round in January 1989, had a club from outside the top four divisions overcome top-flight opposition in the FA Cup.
"They held a Premier League team for 90-plus minutes... It's a huge day for them, for me and for our supporters"
Luton manager Paul Buckle
Luton, relegated from the old first division in 1992 and dumped out of the Football League in 2009, lie sixth in the fifth tier of English football.
Norwich had made six changes from the team that lost 5-0 to Liverpool in the Premier League last week in a clear statement of where the competition ranked in the club's priorities.
For Luton, the occasion was a far cry from their last match, a 0-0 draw with Telford in the Blue Square Premier division.
The gap between the two sides, however, meant little as Luton held off a their opponents before striking late in the second half when Rendell steered home JJ O'Donnell's low cross.
"It's a lot to take in. The players were tremendous today," said Luton manager Paul Buckle, whose team beat second tier Wolverhampton Wanderers in the third round.
"They held a Premier League team for 90-plus minutes.
"It's a huge day for them, for me and for our supporters. Norwich pushed us all the way but we were good for the win in the end. Scotty scored, it's what he does best, but everyone played their part."
The Premier League's bottom club QPR played a second-string team against MK Dons and were comprehensively outplayed by a side 31 places below them in English leagues.
QPR retained only two players from the side that drew 1-1 with West Ham United in the Premier League last Saturday, and were behind after four minutes when Armand Traore put through his own net.
Ryan Lowe latched on to a ball over the top and rifled home a second five minutes before the break, Ryan Harley made it three and Darren Potter profited from appalling QPR defending to fire home a fourth.
The hosts salvaged pride with late goals from Jay Bothroyd and Fabio, although the late rally did little to appease Rangers manager Harry Redknapp.
"It was bitterly disappointing, there is no excuse for conceding four goals at home to MK Dons. It was disgusting," Redknapp said.
