Premier League side Bournemouth have been dumped out of the FA Cup after an embarrassing 3-0 third-round replay defeat by third-tier Wigan Athletic.
Wigan, who won the competition five years ago but have since slipped down the divisions, overcame a weakened Bournemouth side with a first-half effort from Sam Morsy and quick-fire second-half goals from Dan Burn and Callum Elder.
Chelsea won a penalty shootout to beat second tier Norwich City on Wednesday and sneak into the FA Cup fourth round following a tempestuous replay that ended 1-1 after extra time with the Premier League champions reduced to nine men.
Chelsea manager Antonio Conte was fuming at the final whistle after Pedro and Alvaro Morata were dismissed in extra time and two penalty appeals had been waved away, but the Premier League champions regained their composure to win the shootout 5-3.
Eden Hazard stroked home the winning penalty to decide what had begun as a dire spectacle until Michy Batshuayi gave Chelsea the lead in the 55th minute, beforeJamal Lewis levelled in stoppage time for the Championship side.
Norwich manager Daniel Farke thought the game was there for the taking.
"To be honest it's big disappointment, some of the lads are sitting with tears in their eyes in the dressing room," he told the BBC.
Swansea City, the Premier League's bottom side, also reached the fourth round with Wilfried Bony grabbing the winner in a 2-1 victory over Championship leaders Wolverhampton Wanderers.
Jordan Ayew gave Swansea the lead after 11 minutes with a superb goal reminiscent of Ricky Villa's famous Cup final replay winner for Tottenham Hotspur against Manchester City in 1981, but Wolves equalised through Diogo Jota after the break.
