Well that was a thumping victory for Hull FC, so soon after a thumping defeat by Huddersfield as well!

Meanwhile, 2018 winners Catalans looked shocked at Hull's dominance in that second half and Steve McNamara will be disappointed in their performance.

Well we know the first of this season's Challenge Cup semi-finalists. Tomorrow, Hull KR take on Warrington as we find out the second.

We'll be bringing you live text and radio coverage of that tomorrow. For now, thank you for joining us.

Catalans full-back Sam Tomkins told Sky Sports:

"We were poor the first 15 minutes and we clawed our way into it. We knew at half time we had to improve but we had a disgusting second 40 minutes.

"We've got to concentrate on doing something in the league. We've proved we can beat the best times in the competition but we can also be the worst as well.

"We've got to be consistent. We're third in the league and we can't kick off after losing in the Challenge Cup. We've got to focus and rebuild."

Hull FC scrum-half Marc Sneyd told Sky Sports:

"It's crazy, for some reason we step up for the cup games. It's a trophy at the end of the day and we always seem to bring our best rugby when they come around.

"Our attitude and backing up from what we dished up last week, we owed it to ourselves more than anything.

"We know we're a miles better team than last week. It's just us as individuals. We seem to turn up when we want and it's just not good enough."

All over. Hull FC are through to the semi-finals and the holders are out.

That was as good a second half performance as you will see from any Super League side this season and Hull deserve their win.

Catalans looked off the pace, meanwhile.

Hull FC are just seeing this game out as a formality right now.

This result has really knocked the wind out of Catalans' sails.

Marc Sneyd punts over a drop goal as Hull FC's reign of supremacy in this second half continues.

They have been stunning since the restart and Sneyd adds an extra point on the board.

Brayden Wiliame looks to salvage this match with a brave run in at the corner but some tremendous defensive work from Hull FC half-back Albert Kelly holds him up right at the line.

Surely the hosts can't let this slip, now?

Jake Connor comes down awkwardly in an aerial challenge for the ball and looks to have sustained some damage to his right knee.

However he's right back up after a short spell of treatment and ready to continue, much to the pleasure of the home crowd.

Lovely kicking from Marc Sneyd in this game is helping the hosts break deep into the Catalans half and is keeping them pegged back.

Every set of six Hull have, they're bossing. It's the polar opposite of their performance against Huddersfield at the Magic Weekend when they appeared to panic every time they had the ball.

Great stuff, this.

Blimey this game's still in the balance!

Hull FC make a mess of clearing up a loose ball right at the try-line as Joe Westerman frantically kicks the ball away from Sam Kasiano, who dives to try and effectively ground the ball for a try.

Catalans' Tony Gigot knocks on soon after the restart following a Marc Sneyd kick to cheers from the home supporters.

A greasy surface or a lapse in concentration? You be the judge, but it's not going the visitors' way in this second half.

Hull FC's pressure after breaking downfield has been rewarded with a penalty and Marc Sneyd makes no mistake with the boot.

The hosts extend their lead to within a converted try of Catalans, who could do with finding the line themselves and quick.

Catalans have come out of the blocks hunting an early try which could turn the game in their favour as the second half begins to tick down.

However they can't quite work their way to the line as Hull win the ball back on the turnover.

This one's finely poised as it stands, folks.

Out come the players for the second half.

Can holders Catalans remain in the competition or are Hull FC on the way to victory?
