Luton produced the surprise result of the FA Cup fourth round today with a 1-0 win at Premier League club Norwich.
Scott Rendell's 80th minute goal proved decisive in a clash between two sides separated by 85 places in the English football ladder.
Luton is the first nonleague side to beat a top-flight team in the Premier League era. The Blue Square Premier side's victory at Carrow Road means it is only the seventh nonleague team to reach the fifth round of the competition since World War II.
Rendell, 26, has had a largely nomadic career so far -- Luton is his 13th club.
"It's unbelievable to score the winner in a cup tie like this," he said. "It's an unbelievable feeling to come to a Premiership club like Norwich and turn them over. It's fantastic to be part of history. We were aware of it. It's been a fantastic day for everyone."
Norwich was not the only top flight team embarrassed Saturday, as QPR lost at home to MK Dons, 4-2.
QPR manager Harry Redknapp, who made sweeping changes ahead of Tuesday's visit of Manchester City in the league, saw his team thrashed by its League One opponent.
QPR knocked MK Dons out in the third round of this competition last year, but Armand Traore's fourth-minute own goal and Ryan Lowe's 40th-minute effort gave the visitors control at halftime.
Ryan Harley in the 50th minute and Darren Potter in the 56th made it 4-0 before Jay Bothroyd and Fabio pulled two goals back inside the last seven minutes for the Premier League side.
Redknapp lambasted his players after the loss.
"If you look at the team today, what is it? An England goalkeeper [Rob Green], a right-back from Man United [Fabio], a left-back in Armand Traore," he said. "You've got Anton Ferdinand and Tal Ben Haim, then Esteban Granero from Real Madrid. You've got Ale Faurlin, Park Ji-Sung from Man United, Jamie Mackie, Jay Bothroyd and DJ Campbell. Surely they are entitled to beat a team from two divisions down?"
Johnny Heitinga's 90th-minute goal gave Everton a 2-1 success at Bolton. Steven Pienaar's scrappy 18th-minute goal gave David Moyes' men the lead before Marvin Sordell -- whose two goals saw off Sunderland in their third round replay -- squared things nine minutes later.
American midfielder Stuart Holden played his second game since a 16-month layoff caused by a knee injury.
Reading eased into the last 16 with a 4-0 win over Sheffield United.
Noel Hunt opened the scoring in the sixth minute, Mikele Leigertwood's long-range goal against one of his former teams doubled the advantage five minutes before the break, before Hunt and Garath McCleary made sure of the win within nine minutes of the second half starting.
Blue Square Premier side Macclesfield was unable to emulate Luton's exploits, with Jordi Gomez's seventh-minute penalty giving the Premier League's Wigan a 1-0 win at Moss Rose.
There was late heartbreak for League Two's Aldershot at the Championship's Middlesbrough. Danny Hylton's 89th-minute goal appeared to have earned the Hampshire side a replay but Lukas Jutkiewicz added to his 83rd-minute effort with a last-minute winner.
Blackburn was a convincing 3-0 winner at Derby thanks to goals from Colin Kazim-Richards (45), Scott Dann (66) and Jordan Rhodes (71).
Chris Dagnall's goal 20 minutes from time decided another all-Championship clash in Barnsley's favor at Hull.
Lee Novak's 74th-minute penalty gave Huddersfield, under the leadership of caretaker manager Mark Lillis following the sacking of Simon Grayson, the lead against Championship rival Leicester. However, Chris Wood earned a replay for the visitors with a goal eight minutes from time.
