We've got another game coming up on BBC Two...
Hull 18-33 St Helens
BBC One
Hull boss Brett Hodgson on BBC One: "The middle part of the first half, we lost the game. Unfortunate circumstances of Josh Griffin going down but I don't know if the scoreline reflects the second half.
"We think Josh has done his Achilles quite badly, it is a bad one.
"It is the rules of the game, Theo Fages has the opportunity to pick it up, it is fair play."

St Helens' Morgan Knowles on BBC One: "Really good, it was a tough game in this heat. They gave us a bit of a scare in the second half but Regan Grace got the intercept.
"I just try to do some of the hard work, kick chase and knock off the sets. Pleased to get the win."
FT: Hull 18-33 St Helens
Jonathan Davies
Former Wales international on BBC One
A great performance. Hull clawed their way back and had great momentum. That will give them a lot of confidence for the rest of the season.
St Helens will be disappointed that they let Hull get back into it but they were clinical.

It's been incident-packed and high-quality rugby league game in the most testing of conditions.
Hull 18-33 St Helens
All over!
The scoreline might not show it but St Helens were pushed all the way by Hull and are the first team to book their place in next month's Challenge Cup final.

The scoreline does not reflect the performances of the respective teams. It's been a great game.

Jon Gibbon: WEM-BER-LEE! Belter of a cup semi final in the early summer sun and Saints are in the final! Phew!
James Cheeseman: Been a cracking semi-final
Hull 18-33 St Helens
John Kear
Wales & Bradford Bulls coach on BBC One
For any neutrals or anyone who's watching for the first time, this has been a great, great game.
Lachlan Coote
Salt into the wound.
Jake Connor, still thinking about his monumental error, is late to get up for Theo Fages' booming kick and is picked off by Kevin Naiqama.
He plays it on for Lachlan Coote to go in for the easier try of his career.
'Crash Bandi' Coote adds the two.
Hull 18-27 St Helens
John Kear
Wales & Bradford Bulls coach on BBC One
What a finish. It's like watching a thoroughbred in the derby.
Start booking your hotel for Wembley, Saints fans.
Hull 18-27 St Helens
Why did Jake Connor have to force it so early?
Keep your composure, wait for the opening.
Hull 18-25 St Helens
Jonathan Davies
Former Wales international on BBC One
What a last 10 minutes we've had! Hull have thrown everything at St Helens. The difference has been Josh Reynolds.
Regan Grace
Hull on the attack...BUT SAINTS SNATCH!
Jake Connor forces it, trying to move the ball on but Regan Grace reads it and goes the length of the field to cross.
Connor has his head in his hands, Saint are going to Wembley, Hull are going home.
OH MYYY!!
Hull 18-21 St Helens
John Kear
Wales & Bradford Bulls coach on BBC One
These fans in front of us are making enough noise for 10,000 people. They've certainly lifted the Hull side.
Hull 18-21 St Helens
Oh my goodness!
Big plays needed from the big players and Jake Connor has provided it with a inch-perfect 40/20 kick to retain possession.
Hull 18-21 St Helens
A massive eight minutes this.
Cameron Scott
HULL IN AGAINNN!
What a semi-final we have on our hands.
Jake Connor tips the ball on and Cameron Scott jinks left and right before stretching over the whitewash.
But Marc Sneyd sends the kick wide, how crucial will that be?
Saints are capitulating before our very eyes at the moment.
Hull 14-21 St Helens
Hull are now chancing their arm, free-flowing from the black and whites...
