BBC Red Button
Fancy some classic FA Cup action? It's live on the BBC Red Button right now.
Wrexham's upset of Arsenal back in 1992 has just been on. The scenes at the final whistle!
Image source, Getty ImagesBirmingham v Blackburn (12:31 GMT)
Image source, Getty ImagesSome of these go back a while but Birmingham go into this one having won all three of their previous FA Cup meetings with Blackburn in 1932-33, 1934-35 and 2003-04.
In their last meeting Clinton Morrison, Stephen Clemence, Mikael Forssell and Bryan Hughes scored as the Blues cruised to a 4-0 win, while Tugay (remember him folks?) was playing for Rovers.
On a slightly more positive note for Rovers fans, their side has lost none of their last seven away FA Cup matches (W5, D2) since losing against Manchester City in a third round replay in January 2014.
Not quite the immovable object versus the unstoppable force but you know what we mean.
Image source, BBC SportThere will be an upset somewhere on FA Cup third round weekend, surely - but where will it come from?
BBC Sport football expert Mark Lawrenson has gone through all 32 of this weekend's ties and has given his verdict on who might spring a surprise.
For selected matches, including the BBC's two televised games - Liverpool v Everton (16:01 GMT KO on Sunday) and Arsenal v Leeds United (19:56 on Monday) - BAFTA nominated comedian and Ladhood star Liam Williams has thrown a prediction in as well.
There's obviously far too many to list so you can see all of those here.

Rochdale v Newcastle (12:31 GMT)
Neil Johnston
BBC Sport at Spotland
It's a grim, wet day in Rochdale - perfect conditions for an upset as the team 18th in League One host injury-hit Newcastle. The floodlights were on three hours before kick-off and by 12:30 the Crown Oil Arena will be packed.
Newcastle are six-time winners of the FA Cup but so bad is their record in the competition that Rochdale have reached the fifth round more times than their Premier League opponents in recent seasons.
The Magpies have had a terrible festive programme losing all three games. They arrive at Rochdale with a seriously depleted squad but Steve Bruce knows there will be uproar if Newcastle are knocked out by opposition from two leagues below them.
A really good initiative.
