It wasn't always a pretty game, but Wigan and Warrington provided us with one of the most exciting finishes to a rugby league game you could ever wish to see.

A reminder that the Rugby League Forum will continue on this page for another 15 minutes, so stick around for even more reaction the match.

I'll be back for the last of the quarter-finals on Sunday, as Hull FC host Castleford Tigers at 15:00 BST.

Thanks for joining me today. Until tomorrow, goodbye.

We'll be wrapping up this live text commentary fairly soon, but you can continue to follow the Rugby League Forum using the player at the top of this page.

The Forum will carry on until 17:35, so there's plenty more reaction to come.

Warrington head coach Tony Smith on BBC Red Button:

"We were very close in a couple of ways but I suppose when you look back over the game a few of those errors have cost us.

"The spirit was there, they had a real crack, some of my boys were carrying some stuff there. Character-wise, I can't be critical."

On Declan Patton's late miss: "It's all part of the learning process and that's how you become a great player of the future. He'll get better from it, he did some really good things for us today."

Wigan forward John Bateman on BBC One:

"I was watching the screen, I didn't even want to watch the kick.

"That was one of the best feelings ever."

You might never see a more exciting finish than that.

Patton was only 10 metres out when he attempted his drop-kick, but he couldn't quite get his angles right under pressure.

Wigan's hopes of a 20th Challlenge Cup triumph live on.

Declan Patton gets the chance to tie the scores right at the death, but his drop-kick sails agonisingly wide.

Wigan, by the slimmest of margins, are into the Challenge Cup semi-finals.

It's heartbreak for Warrington.

Stefan Ratchford's kick has the distance, but it drifts to the left of the posts.

Warrington will get one more chance the goal-line drop-out.

This is incredible.

Wigan kick the ball out on the full from the restart, giving Warrington a penalty from the half-way line...

Warrington have to score here.

Joe Burgess is trapped in goal, giving Wolves chance to attack from the goal-line drop-out.

This could prove crucial.

Sam Tomkins kicks a drop-goal to extend the Wigan lead to seven points, with Ashton Sims just unable to close the Wigan full-back down.

It looks like being the Warriors' day.

Wigan hooker Michael McIlorum knocks on after being tackled a couple of metres out, and Warrington still have hope.

Wigan start a set of six from the half-way line, after Ryan Atkins is penalised for a challenge on Liam Marshall.

Can Warrington fight back for a third time?

The hosts have never led in this game, and at the moment they're having to defend again.

Wigan are 10 minutes away from the semi-finals.

He couldn't miss from there.

Declan Patton takes his time and coolly draws Warrington level.

A handling error from Ashton Sims looks to have put an end to Warrington's attack, but the hosts recover and flip the ball out to the left-hand side to Tom Lineham.

Lineham's kick-and-chase looks like it will be unsuccessful, but Liam Marshall is penalised for obstruction.

And now, another penalty goes against the visitors. Warrington will go for the two points...

It was a Joe Burgess knock-on which set Warrington up for that Andre Savelio try, and another penalty puts the visitors under pressure again.

This time, Wigan survive the attack, but the momentum has shifted back in favour of Tony Smith's side.

Warrington can't take advantage of the penalty, as a forward pass nullifies the attacking threat.

Having started the half so badly, Wolves are matching Wigan again, but they're finding it very difficult to pick apart the Warriors' defensive line.

Warrington have fought back from 12 points behind to get back on terms in this game before, and now they face another uphill struggle.

Yet another Wigan penalty allows the hosts to build an attack from close to the Warriors goal-line.
