Saturday was not a good for Birmingham City and Aston Villa, as the Premier League pair were both dumped out of the FA Cup by Huddersfield Town and Manchester United respectively.
League One Huddersfield won 2-1 at their Galpharm Stadium, while Premier League holders United came to Villa Park to beat the home side 2-0, with late goals from Cristiano Ronaldo and Wayne Rooney.
But Championship Coventry made the biggest giant-killing of the day with a 4-1 thrashing at Premier League Blackburn Rovers.
And West Brom drew 1-1 at Championship rivals Charlton Athletic.
Fellow Championship side Wolves beat Conference Cambridge 2-1 at Molineux, while Walsall drew nil-all with League One rivals Millwall at the Bescot for a replay at the New Den.
And finally, Chasetown, who are in the fourth tier of non-league football, lost 3-1 to Championship Cardiff, but it was a historical day in the club's history.
