Off the line! Manuel Lanzini gets a shot away after being forced wide, it's going in but it's somehow cleared on the line by James Bolton, who has only just come on as the extra fourth sub!

Peter: Who needs Vardy when you’ve got VAR.

Gareth: VAR needs to be in the Premier League, some teams could go down due to bad decisions - well done to the FA Cup to try VAR.

Steve: Can we stop doubting VAR please. Football referees are no longer a laughing stock! Obvious bad decisions are a thing of the past, pundits will now have to talk about something else. How about a campaign to stop players and manager abusing officials?

Pedro Obiang is urged to shoot from a mile out - remember his goal at Wembley? - he doesn't though. The Hammers build up down the left but it comes to nothing.

Reading cruise through in the end, they will play Sheffield Wednesday in round four.

What I liked about it was John Moss waited, he took his time, he trusted what was being said to him, he made the call and that was it.

I'm perfectly happy with that, I'm perfectly happy with it all.

Still a decent tie, pretty end to end as Shrews captain Abu Ogogo rushes his shot and clips it well wide in the end.

I thought it wasn't a great game of football, and even though Leicester were probably the better side the game will be remembered for what happened with about 12 minutes to go.

The referee pointed to his ear after Iheanacho's goal was called offside and John Moss waited and waited. We'll have to get used to this, but he gives the goal and it was the right decision.

We're not going to get every decision right but the use of VAR will definitely help with a lot of them.

Off the line! Ben Godfrey clears as Mark Noble lofts a header in on goal after Shrews keeper Dean Henderson didn't deal with a corner.

A couple of thousand fans have left at full-time, trains to catch and all that. Will we get a winner or is all the way to pens from here?

Worked well didn't it?

Here it is.

The historic moment where VAR was used for the first time to award a goal in England.

Away we go!

Tonight sees the lowest ever FA Cup attendance at the Madejski Stadium.

League Two Stevenage have brought 608 fans with them along the M4 to watch their side, who currently trail Reading 3-0.

No goals in 180 minutes? Yep? Another 30? Yep.

Steven Shaw: I think that VAR is a great idea. Anything which leads to the right decision being made is a good thing and never mind those who say that mistakes are part of the game. Until they cost your team points, that is.

Paul, Walsall: Would have been more fun if Jamie VARdy had been the scorer of the VAR goal.

Mario: Right. So what happens if the keeper sees the flag up, hears whistle, stops, striker rolls into empty net, and VAR overturns it to allow goal?

Leicester are away at Peterborough in round four, Sheffield Wednesday look like they will be playing Reading.
