Hull 14-21 St Helens
St Helens looking to put the game to bed for the third time as Theo Fages swings a looping pass out wide to Regan Grace but it's forward.
Hull's pulse is weak, but they are still clinging on.

This is a fascinating game of rugby league.

Danny Houghton
Hull seem dead but keep coming back to life like The Undertaker.
Carlos Tuimavave looks like he is tied up by three Saints defenders but somehow wriggles his body away for a stunning offload allowing Danny Houghton to run in unchallenged.
Two more for Marc Sneyd and there is seven points in it.
But how big will that Theo Fages drop-goal prove to be?

That will take the sting out of Hull.

Theo Fages
Huge, huge point for St Helens, Theo Fages, who has been superb today, pops over a drop goal and Hull now need THREE scores to turn this game around.

It's been a tough, tough old game. And it should be in the semi-final of the Challenge Cup.

Biggest takedown of this match so far has been by the ref on Jake Connor.
"If you did less talking, you'd have a great semi-final."

Hull have got a spring in their step, they just need an opportunity to get it over the line.

Hull go to the other end and Manu Fonua is inches from his second try of the day but cannot cling on to Jake Connor's kick into the corner.
Hull force an error from Kevin Naiqama and they get another six.
Can they make it count?

That's when they needed the composure. That'll give them a bit of confidence.

There's one!
It's brilliant from Hull, working it wide with quick hands and the big Tongan Mahe Fonua holds off three Saints defenders to barge over.
And Marc Sneyd curls in the extra two.
This semi-final is still alive.

Saints have a tight defence as it is, how on earth will Hull manage to score three converted tries against them?
30 minutes to try and get them.

What an absolutely fantastic rugby league player Welsby is. What composure. This was the result of constant pressure and it's a fantastic finish.

Jack Welsby
St Helens extend their lead and take a huge step towards Wembley.
Theo Fages scored one and makes this playing it off towards Jack Welsby down the left.
The young centre has plenty of work to do and his arm touches the ground but manages to keep his composure to stretch out and plonk the ball for another Saints try.
Lachlan Coote adds the two and Hull are in big trouble now.
