As if to emphasise the points made by Jon Wilkin and Jonathan Davies, Warrington start building some momentum but then Peter Mata'utia tries a risky offload and gifts possession back to Wigan.

Wigan come back in the other direction but play is stopped because a couple of players need some running repairs following a clash of heads.

They'll have assessments off the field to make sure they're fully fit to continue before they're allowed to return.

Chappy: Another game spoilt

The pressure they (Warrington) are feeling is the expectation.

Everyone expects Warrington to win now (after Wigan's red card).

They have to control the game, build the pressure and manipulate the defenders.

Wigan's energy levels will be good while they're in front, Warrington have to make them work.

Warrington are second-best in most facets of the game right now.

They need a reset.

They've got the spinning wheel on the computer at the moment, they need to shut it down and start again.

James Harrison is penalised for gathering the ball from an offside position after a Wigan kick bounces into space, and Harry Smith kicks the two points from the tee.

Artie Fishall: I realise screaming "stop panicking!" at someone who's panicking is the worst possible way to get them to stop panicking, but Warrington need to stop panicking

Patience is the key for Warrington here, with that player advantage following Kaide Ellis' early red card.

They've been guilty of a couple of basic errors so far and haven't especially threatened Wigan's try line.

It’s 100% a missed opportunity.

It’s probably the right play but just poor skills let them down there.

Wigan are relying on those errors from Warrington.

As Warrington look to respond, George Williams fires a pass to Ben Currie five metres out but the Wolves' second-rower is unable to grasp it.

One thing to note about the try-scorer... Toby King is on loan at Wigan this season FROM Warrington.

This has already turned into a classic cup tie between two massive rivals.

His actions there have really cost the Wigan team who have been on top.

He sticks his forehead on his nose and Ratchford is bleeding.

It's poor, it's terrible.

So Wigan will be playing the next 73 minutes with 12 men.

Surely advantage Warrington, although the Wolves drop the ball in midfield and that allows Wigan to attack the Warrington line.

A knock-on at the play-the-ball gives it back to Warrington, who then botch their own restart and Wigan have it back!

You just don’t need to do that.

Just stupid play.

He had a couple of goes at it and will look back thinking what have I done.

Wigan push Connor Wrench beyond his own dead-ball line to force a goal-line dropout.

There's a bit of a melee afterwards and Stefan Ratchford emerges with a bloody nose.

Kaide Ellis appeared to send his head towards Ratchford and he might be in trouble... and it's red!

A fascinating battle ahead between the two main playmakers, Wigan's Harry Smith and Warrington's George Williams, especially if the weather does turn.

Smith kicks high to the corner at the end of a Wigan set but Warrington's Josh Thewlis takes it very, very well.

Wigan kick from halfway at the end of their opening set and Warrington respond by getting into the Warriors' 20.

A solid start.

Jon Wilkin

I used to love these games.

I’m looking forward to two exciting teams with some great players really going at it.

The opening exchanges are always telling in these games and they are even more so today.

Warrington captain Stefan Ratchford kicks into Wigan territory and we're under way in this Challenge Cup quarter-final.

It's dry and humid at the moment but there's talk of rain and storms on the way in England's north west.
