Game on!

Coventry manager Mark Robins had just been forced into making a change after Fabio Tavares was taken off due to an ankle injury.

Kasey Palmer sends in a cross that Martyn Waghorn manages to poke into the path of Ben Sheaf, who then drills the ball first time into the Wrexham net.

Sweden forward Viktor Gyokeres has come on for Tavares.

It should be 1-1 with the chances they've had. Who was marking Isak? He didn't seem to have any conviction on the header.

Been a great opening 10 minutes to this one. It was end to end action at Old Trafford last night and we're seeing similar here this evening.

It's not easy for Jamaal Lascelles when he hasn't played much football to be coming in in a game of such importance.

Newcastle should lead!

The Magpies go flying to the other end of the pitch, Alexander Isak meets Javier Manquillo's cross with a towering header, but Cameron Dawson keeps it would with a reaction save.

At the minute, Sheffield Wednesday are competing. They've got to enjoy the ball when they get it. They must be thinking 'how do we stop Newcastle?' Well they're giving away far too many free-kicks.

Palmer gets on to it brilliantly, he pulls the trigger and just pulls it wide. That was a great opportunity. He has scored recently but wasn't able to do it there.

First sight of goal comes Sheffield Wednesday's way.

A loose throw-in from Jamal Lewis is intercepted by Liam Palmer and the space opens up for a shot, but the Owls skipper drags wide from the edge of the box.

Ben Mee has a shot at goal which hits the right post for Brentford after West Ham make a mess of clearing their lines from a free-kick but it wouldn't have mattered anyway as the hosts were offside before the ball even got to the defender.

We know Isak is the real deal so it will be an interesting battle between him and McGuinness tonight.

Alexandre Isak, back in the Newcastle team for the first time since September, is dragged back by Mark McGuinness on the touchline.

That will be a heck of a battle tonight.

The resulting free-kick is headed over by Elliot Anderson.

Sheffield Wednesday in their traditional blue and white striped kit tonight.

Newcastle are playing in their white and green Saudi Arabia kit.

This is a Sheffield Wednesday team in really good form right now so it could certainly be an occasion given all the changes Newcastle have made.

Nottingham Forest

Nottingham Forest manager Steve Cooper speaking to BBC Radio 5 Live: "I think we have got ourselves to blame, so we have to accept the scoreline because of the individual errors we made for their goals and the chances we missed.

"We can have no excuses for the result. You can't give away the chances we did and miss the chances we had and expect to get a positive result. Even when we went 2-0 down I thought we were still in the game but we didn't show enough fight to get back into the game, we went down too easily and that was just as disappointing as the chances we missed today and the ones we gave away.

"Just because someone did well or poorly today, it doesn't necessarily impact the next game because it will depend on the game plan and what we need. It is hard to say if someone played well when you lose 4-1."

Away we go at Hillsborough.

Another goal in the 17:30 matches.

Luton Town, who are seventh in the Championship, have fallen a goal behind to the side who currently prop up the league, Wigan.

Callum Lang is denied by Luton goalkeeper Ethan Horvath from a corner but the Latics keep the attack alive and midfielder Tom Naylor turns the ball in from close range.

Brentford send Saman Ghoddos free down the left and his cross is a good one and somehow, with his wrong leg and somewhat ungainly, Angelo Ogbonna manages to hack the ball clear and the Hammers survive.

West Ham's Tomas Soucek, able to carry on after taking an early kick on the knee, gets into a good position into the penalty area but his pass to Lucas Paqueta is overhit and his team-mate can't keep the ball in.

We have seen some great results in the FA Cup this season. It is a free hit at a team who are absolutely flying. The Newcastle supporters have come down in their numbers, they've got great support. Sheffield Wednesday will not be quiet today, they can smell a scalp.

Newcastle have made a few chances. Both teams are full of confidence and Sheffield Wednesday will give them a game.

The away fans are jubilant.

Elliot Lee looks like he is sizing up to cross into the box but the ball goes beyond Coventry goalkeeper Simon Moore and into the back of the net to double Wrexham's lead.

Coventry have had decent chances in this game too. A great cup tie in progress.
