Graham Dorrans does the business as Baggies book fourth-round cup berth

But Scotland international Graham Dorrans, with his third goal in five days, and substitute Chris Wood both struck within the space of five minutes in the closing stages to inflict Huddersfield's first home defeat of the season.

Aston Villa manager Martin O'Neill hailed another crucial contribution from winger Ashley Young as his side overcame Blackburn 3-1 to reach the fourth round of the FA Cup. Young was restored to the starting line-up after being suspended for the midweek home defeat against Liverpool, having incurred five yellow cards this season. But the England player quickly made an impression in creating the opening two goals for Nathan Delfouneso and Carlos Cuellar, with John Carew netting the fourth from the penalty spot. O'Neill said: "Ashley set up the opening two goals and he is a top-quality player who is so important to us."

Coventry City held cash-strapped Portsmouth to a 1-1 draw at Fratton Park to set up a richly-deserved replay.

The Sky Blues went ahead against the run of play after half an hour thanks to a brilliant 20-yard effort from David Bell. Kevin-Prince Boateng nodded a leveller for the Premier League side in first-half stoppage time, but the troubled 2008 FA Cup winners never looked like finishing off Chris Coleman's resilient side.

There is too much FA Cup tradition at White Hart Lane for anyone to take the old competition anything but seriously. And Tottenham manager Harry Redknapp got the club's 2010 challenge rolling when he sent out his strongest side to rout Coca-Cola Championship strugglers Peterborough United 4-0.

Two goals from Niko Kranjcar, the inevitable strike from Jermain Defoe and a late penalty from Robbie Keane were the vital statistics in a one-sided cup tie. But it was the businesslike way Spurs went about their work which suggested that a ninth FA cup triumph is in their sights this season.

Ipswich progressed to the fourth round of the FA Cup with a hard-fought victory over nine-man Blackpool at Bloomfield Road.

Jack Colback opened the scoring for the visitors in the third minute with a right-footed shot from the edge of the area, although Blackpool were unlucky not to be level at the break after they were denied by the woodwork three times. Gary Taylor-Fletcher saw two long-range efforts hit the crossbar, while Charlie Adam hit the post with a first-half penalty.

The hosts did equalise early in the second half through Brett Ormerod's header, but their hard work was soon undone as Ian Evatt and Rob Edwards picked up straight red cards. Ipswich capitalised on the dismissals, with Owen Garvan firing home the winner from a free-kick with 13 minutes left.

Carlisle were given a standing ovation at Goodison Park for their display against Everton, who were frustrated for long periods by Greg Abbott's defiant League One side. Two late goals gave Everton a flattering 3-1 victory when the Cumbrians were already thinking about a money-spinning home replay.

James Vaughan put Everton ahead early on and it should have been plain sailing for the Premier League side after that. But Kevan Hurst's scuffed equaliser gave Carlisle hope, and they held out until the final minutes when Tim Cahill netted his 50th goal for Everton ahead of an injury-time Leighton Baines penalty.

Fraizer Campbell struck his first goals in three months to head Sunderland into the FA Cup fourth round at the expense of non-leaguers Barrow. The Blue Square Premier side had put the wind up Steve Bruce's men in a storming start which saw Phil Bolland, Paul Bond and Marc Goodfellow all come close. But Steed Malbranque's 17th-minute opener set the home side on their way and Campbell's brace early in the second period saw the Barclays Premier League side home 3-0, breaking the hearts of around 8,000 away fans massed in the south stand.

Championship side Preston North End, who sacked manager Alan Irvine last week, thrashed Colchester United 7-0 with a hat-trick by Jon Parkin .
