Hull City beat Sheffield United 2-1 in a fifth-round replay to reach the FA Cup quarter-finals for the first time in 37 years on Thursday.
A bizarre own goal from Kyle Naughton gave Premier League strugglers Hull the lead after 23 minutes although his wayward header off the crossbar did not appear to have crossed the line.
Billy Sharp levelled soon afterwards for Championship (second division) United but Peter Halmosi struck 10 minutes after the break to send Hull through to face Arsenal or Burnley in the last eight.
The first match ended in a 1-1 draw.
