Jack Welsby attempts to send Tee Ritson through as St Helens keep up their early charge.

But soon after Hull make their pressure count as Alex Walmsley spills the ball in the process of rolling it to James Roby and the hosts win back possession.

A good start, this.

St Helens win a set of six deep in the Hull FC half.

Jonny Lomax offloads to Jack Welsby but the talismanic Saints man is well held up by Carlos Tuimavave.

Welsby later works it wide to Tommy Makinson, who can't quite keep it alive.

Referee Chris Kendall blows his whistle and St Helens kick us off.

Saints are wearing a light blue change strip which, from a distance, merges into the black and white of Hull FC to my eyes!

Anyway, more Challenge Cup rugby league. We're in for a treat.

Right, here come the players.

Kick-off is imminent.

How do you see this one panning out? Do you think Tony Smith's Hull FC can put a stop to St Helens' decent form?

Or are Saints on their way to a certain semi-final spot?

This is the greatest cup competition in rugby league. This is the game you tune in to.

I’ve been fortunate enough to lift that trophy and there are players in the Hull team who have lifted this trophy, showing they have had success.

It’s a one-off so there's nothing to lose. In the league on a week-to week basis you can go back to the process to fix things, but in this it’s today only.

That gives Hull a chance. They start as underdogs but they’re here and they give themselves a chance.

You don't dominate the sport as much as St Helens have in recent years without knowing a thing or two about dealing with pressure.

Saints boss Paul Wellens is pleased with his side's recent return to form coming into today's trip to the MKM Stadium.

"One thing that this group has been accustomed to in recent years is playing in do or die situations or playing in knockout situations, whether that's a Grand Final, Challenge Cup final or play-off games," Wellens told BBC Radio Merseyside.

"The players know what it takes to play at this level and under this type of pressure.

"Rugby league is a game that if you take your eye off the ball, it can bite you on the backside pretty quickly.

"We keep our feet on the ground and keep working hard for each other. If we continue to do that then we are confident that we can achieve more success moving forward."

St Helens boss Paul Wellens names an unchanged side following their derby win over Wigan last week.

St Helens: Welsby, Makinson, Hurrell, Percival, Ritson, Lomax, Dodd, Walsmley, Roby, Lees, Sironen, Batchelor, Knowles

Interchanges: Mata'utia, Lussick, Paasi, Bell

This is how Hull FC line-up this afternoon as Tony Smith starts Davy Litten at full-back, while Tex Hoy moves into the halves with Jake Trueman.

"Inevitable".

That's how Hull FC boss Tony Smith has branded St Helens' recent return to form following a poor spell earlier in the season.

After beating NRL champions Penrith in February, Saints lost five of their first 10 matches of the season.

They have since won four straight games, including their derby win over Wigan.

"Anybody with any sort of consideration as to how big it was of them to go to Australia for their pre-season and play two games against NRL teams and come back to start our season [knows] it is a big ask for anybody," he told BBC Radio Humberside.

"It was always inevitable that they were going to get back on a roll and on track because that would have taken a lot out of them, that's for sure."

A reminder that we're set for our second Challenge Cup quarter-final of the day.

Hull KR put their recent Super League woes aside to beat Salford Red Devils and reach their second successive Challenge Cup semi-final earlier on Saturday.

The greatest game returns and it's live on the BBC.

Hull KR's tie against Salford warmed us up. Now the action in the Challenge Cup continues.

Hull FC take on a St Helens side that are in fine fettle of late, and come into this quarter-final tie off the back of a morale-boosting derby demolition of Wigan last week.

But who's going to join the Robins in the semi-finals?

Kick-off is coming soon.

Rugby league is a fast and dynamic game, which involves great strength, stamina and skill, and is played through the summer, so no muddy pitches, or cold, wet training nights!

With so many variations, you don't have to play the full version of the game to be part of it.

Whatever your age, gender, fitness level or technical ability there is a version of rugby league that will suit you.

Playing rugby league has many benefits, including keeping fit, meeting new people and maybe even progressing to a higher level.

Although rugby league shares similarities with rugby union, it is important to see them as different games, and as such, each has its own unique set of skills. Look at the rules to get a feel for the game., external
