Notts County produced an FA Cup replay shock with a 2-0 win at Premier League Wigan Athletic on Tuesday to earn a place in the fifth round.
Another fourth round replay also produced a shock with Championship Crystal Palace, who were recently plunged into a relegation dogfight after a 10-point deduction for going into administration, ousted top-flight Wolverhampton Wanderers 3-1 at Selhurst Park.
Danny Butterfield, whose nominal position is as a full-back and who had scored once in 6-and-a-half years, netted a second-half hat-trick in just 6 minutes for Palace who will take on Aston Villa for a place in the quarter-finals. Notts County's reward for their victory over Wigan is another crack at Premier League opposition in the shape of Fulham.
Spurs travel to Leeds on Wednesday night to complete the draw.
