Nikola Zigic heads Birmingham into the lead! But no, it's disallowed after the big man bundles over a defender in the build-up. Plenty of pushing and pulling in the penalty area.
League One Bradford City take the lead at The Den as Billy Knott pounces to score from close range from James Hanson's corner. The Bantams have not reached the fourth round of the FA Cup since 1999-00. If the score stays like this for the next 84 minutes then they will do just that.

Blackburn take an early lead in this all-Championship tie. Midfielder Chris Taylor stoops to head in Craig Conway's cross.

"Conference teams are improving all the time, so their standard is very close to that of League Two or even League One. So the gap may not be as big as it quite obviously looks in terms of the tables. Most non-league players have played in the Football League.
"Gateshead can play very good football. I think we'll see a very strong performance from the visitors but I'd be very surprised if we see an upset. I expect to see a renewed zip in the West Brom play as a new manager has been appointed."
No signs of early nerves from a much-changed Swansea side, with Bafetimbi Gomis firing an early effort just wide.
Gateshead have an early free-kick in a decent spot after James Morrison blunders into a challenge on winger Alex Rodman. What can the Conference side work from this?
Not a lot. John Oster plants the set-piece straight into the gloves of Boaz Myhill in the Baggies' goal.
Birmingham boss Gary Rowett said before the game that his side had prepared by training on a 'very, very bad pitch' - and that may have been wise. The surface at Croft Park is certainly not silky. Hit Zigic!

"Blyth have been on cup runs in the past but today will be a very difficult game. They must start with a high tempo and try to get in behind that Birmingham back line."

BBC Final Score reporter Naz Premji tweets:, external BREAKING NEWS: Barnsley v Middlesbrough delayed kick off 3.15pm. Structural problems in West Stand.
There may be some angry Bradford fans stuck on the M11 if these tweets from the club's official Twitter page are anything to go by.
The messages read:, external "Unfortunately it would seem a lot of City fans have been caught up in the M11 closure on their way to today's Millwall game. With the M11 not set to re-open until approximately 6pm, however, the decision has been made NOT to delay today's kick-off."
Tony Pulis emerges out of the Hawthorns tunnel to applaud the West Brom fans, who return the compliment, before the Welshman heads up to a seat in the stands.
We are under way! Every goal coming your way...

Still time to get your half and half scarf...
On the BBC Sport Facebook, external page, here's where some of you think the upsets will come:
John Commander: Reckon the upsets will come at Huish Park and Prenton Park as Yeovil will beat Man Utd and Tranmere will beat Swansea.
Allan Thomas Woodward: TRFC could produce a cup shock against Swansea at Prenton Park.
All the noise at Pride Park ahead of kick-off is coming from the away end. Conference side Southport have taken 2,700 fans to the Championship club - their average home attendance barely scrapes over 1,000. The streets of the Merseyside town will be empty this afternoon...
The teams are out! One of the narrowest tunnels I've seen at Croft Park. No room for error...
Lovely conditions at Cambridge - ideal for an old-school Cup tie...
