Hello! Bit of a shoot-on-sight policy for the hosts - we've seen a few audacious attempts, with the latest coming from Han-Noah Massengo, whose dipping volley from distance drops just over the bar.

Blackpool should be two up.

Having scored, Keshi Anderson sets up Shayne Lavery at the near post but he puts it wide.

The Seasiders look dangerous on the break.

Conor Gallagher has taken a smack to the face and he needs patching up. He'll have a nice shiner in the morning...

Oooh! Alex Scott's inswinging corner almost catches out Paulo Gazzaniga at the front post, with the Fulham stopper just getting across to palm it behind for another.

Festy Ebosele has looked bright for Derby. He skips past the full-back on the right, gets to the byline and wins a corner as his cut-back is scrambled clear at the near post.

A first decent chance for the Premier League side but Jay Rodriguez fires wide. This one is starting to open up a touch.

Will Hughes and Sheyi Ojo go sliding in for a loose ball and the tackle isn't too clean from the Palace midfielder.

Benik Afobe then smashes another good chance over the bar from close range. Millwall are causing problems.

Fulham are giving the ball away in dangerous areas and making hard work for themselves. Han-Noah Massengo pinches possession for Bristol City and is then fouled on the edge of the box.

Chris Martin whips this one on target but it's easy for goalkeeper Paulo Gazzaniga.

Much better from Mansfield who are enjoying their best spell.

John-Joe O'Toole turns well in the box before crossing to the back post but Rhys Oates cannot connect on the stretch.

Great noise at The Den. Millwall look full of energy but Palace are doing well to soak it up. They are starting to take control of possession now.

Hartlepool haven't reached the fourth round since 2009 but they've settled down after conceding early.

The League Two club beat Wycombe and Lincoln from one level above to reach this stage but they're yet to impose themselves on their Championship opponents.

Ahhh, it's a golden chance for Coventry City skipper Matt Godden.

He's completely unmarked in the box when it comes to him but he skies it over the bar from close range. Has to score!

Todd Kane is then played in a few moments later. He goes down under contact in the box but nothing given. Would have been soft.

Couple of half chances for the visitors, first as Josh Koroma forces Nick Pope into a save and then as Jordan Rhodes almost chases down a clearance from the Burnley goalkeeper.

Straight off! Sheyi Ojo wins Millwall a corner on the right as his early cross is blocked.

Jack Butland is then scrambling as the corner comes in and it bounces off the top of the crossbar. Cheeky.

Decent start from Bristol City. Youngster Alex Scott is getting involved, with the 18-year-old's direct running earning the hosts a free-kick. He fancies a pop from 35+ yards too...

Nahki Wells pulls rank and whips one just over the crossbar.

Off we go at The Den. Palace are wearing their commemorative FA Cup shirts to celebrate the 150th anniversary.

No sign of shock o'clock at Mansfield.

Middlesbrough have had five attempts - three on target - and taken control.

Their opponents have yet to register an attempt on target.

It's a wet one in Lancashire, with both sides looking to impose themselves and find a foothold in the game early on. No real chances so far.

I've really enjoyed watching Crystal Palace this season. The style change has been good and the recruitment has been unbelievable. They are young and full of energy and with Marc Guehi, it means they can push forward without having to worry about getting done for pace at the back.

Coventry City finally get the ball down and play after soaking up relentless pressure from Derby in the opening 10 minutes.

Ben Sheaf then gives it away sloppily in the middle and it's back with derby keeper Ryan Allsop.
