A Brede Hangeland goal late in extra time gave Fulham a hard-fought comeback victory over Blackpool at Bloomfield Road.
Chances were few and far between for most of the first half, and Blackpool goalkeeper Matt Gilks denied Hugo Rodallega from point-blank range just after the half-hour mark in the first real opportunity of the match.
On 35 minutes Fulham were unlucky not to go ahead as Giorgos Karagounis put in a corner that Chris Baird got his head on, but it shaved the post of the home goal as visiting boss Martin Jol went in the happier manager at half-time.
The game struggled to spark into life for the majority of the second half as both teams cancelled each other out and chances were few and far between on a really poor pitch at Bloomfield Road.
Blackpool went ahead through Nathan Delfouneso on 82 minutes, as the on-loan striker found space in the penalty area and prodded the ball into an empty net following a ball into the box from Stephen Crainey.
With the last kick of normal time, Kieran Richardson hit a screamer from outside the penalty area into the bottom right corner of the net to send the game into extra-time.
Blackpool started extra-time strongly and put their Premier League opponents under real pressure, with Mark Schwarzer having to make a keen double-stop to prevent Gary Taylor-Fletcher from scoring.
The veteran keeper was smart again to stop Tom Ince when the Blackpool ace was in on goal, but Fulham went ahead with 115 minutes on the clock.
Damien Duff swung in a corner and Hangeland rose highest at the near post with the ball looping into the net, and that goal booked Fulham a fourth round date against West Ham or Manchester United.
