FC United of Manchester's dream of a third-round tie at Old Trafford is still alive after Sam Ashton saved a late penalty against Brighton in the 1-1 FA Cup draw at the Withdean Stadium.
Gus Poyet's men - the League One leaders - looked on course to complete a comeback victory when they were handed a spot-kick in the last minute. But Elliott Bennett's attempt was kept out by Ashton as the visitors breathed fresh life into their Cup campaign.

Their momentum was checked in the second half when Scott McManus was sent off for throwing an elbow, and their resistance was finally punctured when the veteran Mauricio Taricco knocked in an 83rd minute equaliser, before Ashton's late heroics ensured a replay at Gigg Lane.
Loan signing Josh Walker made himself an instant hero by setting Stevenage on the way to a 2-0 victory over 10-man AFC Wimbledon.

Luke Moore wasted a glorious chance to level before sub Yemi Odubade booked Stevenage's place in the third-round draw, while Dons' Ed Harris was dismissed for two yellow cards.

The home side took the lead when Ian Henderson crossed for David Mooney, but that wasn't the cue for the floodgates to open - and the visitors were unlucky to be on the losing side after Jamie Gosling squandered a late chance.
