Walsall's best FA Cup runs have seen them reach round five, last in 2002–03
Leicester won the competition for the first time in 2021
Promise Omochere
The answer is NOT AT ALL!
Danny Andrew delivers a peach of a cross from the left and Promise Omochere is all alone to dive and head it in from six yards.
Omochere got the winner in the last round at home to QPR, and he is delivering again in the FA Cup.
It's only two League One sides, but Fleetwood are beating Sheffield Wednesday!
Southampton 1-0 Blackpool
Jo Tessem
Ex-Southampton player on BBC Radio Solent
Sékou Mara needs to keep the ball better. He is making it too easy for the defenders.
Sheff Wed 0-0 Fleetwood
Big, big chance for Fleetwood.
Brendan Sarpong-Wiredu is unmarked to meet a free-kick six yards out but heads over and into the travelling Cod Army.
How costly could that be?
Fulham 0-1 Sunderland
Are these missed chances going to cost Sunderland?
It's Patrick Roberts and Amad Diallo combining again before the latter's shot is blocked at the near post.
Blackburn 2-1 Birmingham
Almost an instant leveller for the visitors as Tatith Chong bursts into the box and the ball sits up for him nicely, but his effort is straight at Thomas Kamisnski, who punches it away.
Southampton 1-0 Blackpool
Encouraging signs for Blackpool. The Championship strugglers have started the second half on the front foot and Southampton have work to do.
Fulham 0-1 Sunderland
Chances at both ends at the Cottage.
First Abdoullah Ba scuffs his effort for Sunderland before Harry Wilson's effort forces Anthony Patterson intro a flying save.
Elijah Adebayo (49 mins)
The coolest penalty you are likely to see, despite the circumstances, has levelled the scores after a clumsy challenge in the box from Bryn Morris.
It's a seventh goal of the season from Elijah Adebayo who holds his nerve until the keeper dives and rolls it in the opposite direction. Game on.
Fulham 0-1 Sunderland
As it stands a Sunderland win at Fulham would be the shock of the day. The Cottagers certainly had good chances in the first half and they have started the second on the front foot.
Sunderland centre-back Dan Ballard does well to recover to thwart a dangerous attack.
Sam Bell
It's now two brilliant goals for Sam Bell. The youngster shows incredible class to bring down a cross and in one fluid movement dink a sumptuous finish past David Button with his next touch.
He's on for a hat-trick on his first start as a forward.
Magic of the cup...
Joe Rankin-Costello
Rovers in front right at the start of the second half!
Poor play from Blues and Krystian Bielik in particular as they dwell on the ball near their own box and Joe Rankin-Costello punishes them as he finds the bottom corner with a daisycutter beyond Neil Etheridge.
A first goal since August 2020 for the defender. A collector's item!
Blackburn 1-1 Birmingham
A half-time change for the hosts as Tyrhys Dolan is thrown on in place of Ryan Hedges.
New loan signing Sorba Thomas was also introduced to the Ewood Park crowd during the break. He's ineligible for this one after playing for Huddersfield in the last round.
Back under way in the 3pm games.
Bristol City 2-0 West Brom
Sam Bell, in for departed striker Antoine Semenyo, curled home superbly to break the deadlock after some hesitant Baggies defending.
Then Okay Yokuslo missed a header for the visitors moments before Alex Scott doubled the advantage with a close range finish after Nakhi Wells had send Mark Sykes through to cross into the centre.
Max O’Leary kept out Daryl Dike before the break and Carlos Corberan has his work cut out in the next 15 minutes if Albion are to prevent the Robins claiming a third last-16 place in five seasons.
Luton 0-1 Grimsby
The Hatters have pinned the visitors back for long periods of this first half and dangerman Elijah Adebyao fizzed one effort over and saw another thwarted by a superb block from Luke Waterfall while Dan Potts saw a header chalked-off by the flag.
Grimsby keeper Max Crocombe was called into action on several occasions while at the other end his counterpart Ethan Horvath denied Bryn Morris on a rare foray forward from the visitors before Gavan Holohan lit the touchpaper with a far-post header to put the visitors ahead at the break.
Grimsby are 57 places below Luton in the football ladder and haven't been in the last-16 since 1996. This is what the FA Cup is all about, right?
HT: Fulham 0-1 Sunderland
Looking back at the replays it may well have been an Achilles injury for Sunderland top scorer Ross Stewart. He left the field on a stretcher.

Sunderland deserve their lead.
Fulham started well, but Sunderland scored and since then, they've been excellent.
They could have scored more.
HT: Southampton 1-0 Blackpool
Jo Tessem
Ex-Southampton player on BBC Radio Solent
Blackpool have given Southampton some issues. The Saints could have problems.
Fulham 0-1 Sunderland
Jack Clarke's early goal means the upset is on at the break.
Sheff Wed 0-0 Fleetwood
The home side are leading in all the main statistics, except the most important one.
