What a wonderful weekend of rugby league we've had.

After Wigan triumphed in one of the most tense games you could ever wish to watch on Saturday, Hull FC produced a tremendous performance to knock out the runaway Super League leaders.

A reminder that the Rugby League Forum will run on this page for another 25 minutes, but that's all from me for now.

Thanks for joining me this weekend. Until the next time, goodbye.

Those semi-finals will take place on the 28 and 29 July.

We'll be back with full live text commentary of both those games next month, alongside BBC TV coverage.

BBC Two's coverage of today's game will be drawing to a close soon, but fear not, for the stream on this page will carry on for another 30 minutes for the Rugby League Forum.

Just keep watching for more reaction to today's game and the semi-final draw.

Hull's reward for winning today is a game against Leeds Rhinos in the semi-finals.

In the second semi-final, Wigan Warriors will play Salford Red Devils.

And now, we're straight into the draw for the semi-finals...

Hull FC captain Danny Houghton on BBC Two:

"We knew that we were going to have to play for 80 minutes against a temamthat's probably been the form team of the competition.

"Fair play to our boys, we dug deep and we deserved that win I think.

"The memories we got from last year is something that can live forever, and if we can do that again, it takes a special team to do that, so that's our goal."

Hull FC's defence of the Challenge Cup lives on with a hugely impressive victory over Super League leaders Castleford.

Tigers head coach Daryl Powell will be disappointed with the number of errors his side made, but that shouldn't draw attention away from a very professional performance by the hosts.

Castleford have fought back bravely, but it looks like Hull will hang on for the win.

Greg Eden momentarily has a bit of space on the left, but Shaun Michaels makes the tackle and forces the winger to knock on.

Castleford are having to take a few risks now, and it nearly pays off for them, as Michael Shenton's offload nearly puts Luke Gale over on the final tackle, before a Hull defender gets there to bring him down.

Hull need to make good territory on this next set.

This is an audacious drop-goal attempt from Hull's Jake Connor, and he nearly makes it too.

From a long way out, Connor swivels and launches the ball towards the posts, only to see it drift narrowly wide.

Castleford pin Hull back deep with the kick on fifth tackle, but they were never close to threatening to score there.

Hull advance to halfway and again launch a high kick towards Greg Minikin, who takes the ball cleanly.

There's only 15 minutes left for the Tigers to get back on terms here.

Adam Milner concedes a penalty for holding down Hull forward Mark Minichiello.

The hosts are sticking with their tactic of kicking the goals where they can, and Jake Connor once more sticks the ball through the uprights.

We are in for a thrilling finish to this game.

Josh Bowden almost breaks through the Castleford line, but he's wrapped up around his ankle at the very last moment.

Hull get another chance though, as they are awarded a scrum for a Castleford knock-on.

He doesn't look happy about it, but Castleford's Ben Roberts concedes another penalty for holding Albert Kelly down after the tackle.

For the first time today, Jake Connor misses his kick and the scores remain level.

Connor make his fifth successful kick in five attempts to tie the scores up at 18 apiece.

It was Grant Millington's knock-on that set Hull up with good territory, before Mike McMeeken was penalised for holding on in the tackle.

And just as I say they're on the back foot, Hull get chance to level the scores as another Castleford penalty gives Jake Connor the chance to kick his third penalty.

Hull make good ground on their first set since falling behind, but Albert Kelly gets too much on his kick and it's an easy take for Greg Minikin.

The Airlie Birds are on the back foot here.
