Well, with one clinical attack Wigan have thrown the gauntlet down.

Hull KR will want to reply in a hurry.

On the previous tackle, Peta Hiku shot out of the line, so he sprinted up 30 yards and then he had to sprint back 30 yards.

Then he got himself in the wrong position, he showed too much of the outside shoulder and Wardle took it.

He's left too much for himself to do.

Wigan have got away with a lazy forward pass in their own half.

Hull KR are punished of being offside and give away the penalty.

Wigan kick for field position and have the first real attack of the game.

What can they do with it?

Hull KR's Jai Whitbread tried to punch through the middle of Wigan's defence before the ball is swept left by Hull KR.

A big up-and-under kick is defused by Wigan and both sides are feeling their way into this one.

I'm really looking forward to this game. It will come down to composure, completed sets and a good kicking game.

Discipline on a very fast track will be crucial because one silly penalty or indiscipline will put you under pressure.

Wigan are shifted right in their first set before kicking early to try catch Hull KR out.

The kick is deep but well fielded.

And off we go.

Hull KR get this semi-final up and running under blue skies scattered with clouds in Doncaster.

Both sets of players have walked out onto the pitch at the Eco-Power Stadium in Doncaster.

It's difficult to call - if you'd have asked me a couple of weeks ago after the Hull KR victory over Wigan, Id have said they are the favourites.

But after last week, with them getting beaten and Wigan being unbelievable, I'd probably say Wigan this week.

Both teams clash in so many areas on the field, they've got really exciting match-ups.

What I see the game about today is the historical quality and pedigree of Wigan versus the rising pedigree and quality of Hull KR that hasn't arrived at its destination yet.

Is this the next step on Hull KR's journey towards being one of the top teams in this era?

Hull KR make two changes from the defeat by Warrington last time out.

In come Elliot Minchella and Tom Opacic, with Kelepi Tanginoa named on to the bench while Jack Broadbent drops out.

Hull KR: Evalds, Burgess, Hiku, Opacic, Hall, May, Lewis, Sue, Litten, Whitbread, Hadley, Batchelor, Minchella.

Interchanges: King, Parcell, Luckley, Tanginoa.

There is just the solitary forced change for Wigan after their big win against Huddersfield last week.

Liam Byrne is suspended for this one, with Ethan Havard coming in.

Wigan Warriors: Field, Miski, Keighran, Wardle, Marshall, French, Smith, Havard, O'Neill, Thompson, Nsemba, Farrell, Ellis.

Interchanges: Mago, Leeming, Dupree, Walters.

Mikey Lewis spoke about 'stepping up to the next level', but it seems Wigan are only too aware that the Robins have done that and some over the past year.

Warriors captain and influential back-rower Liam Farrell has seen first hand just how the Robins, coached by ex-Wigan half-back Willie Peters, have matured into a genuine Super League force.

"They're a club who are rapidly trying to move forward," Farrell told BBC Radio Manchester.

"They've made some great signings and their performances have matched that, and they're a club who last year performed really well and they've taken it to another level, outstanding talent with Mikey Lewis leading the way.

"But right in the front of our memory we had a tough game against them a few weeks ago so it's fresh in the moment. We've learned a hell of a lot from that game and [need to] make sure we fix it up."

Hull KR went on to lose the Challenge Cup final last season, with a drop-goal from Leigh's Lachlan Lam sealing the Leopards' famous victory in the decider.

For the Robins, this semi is a continuation of their 2024 Challenge Cup reunion tour, having knocked out Salford and their 2023 conquerors Leigh en route already.

Wigan, who top the Super League table after 10 games, have reason to be at least a little confident after getting the better of Warriors a few weeks ago at Craven Park.

"We've got to step up and be on our A-game," said Hull KR's Mikey Lewis.

"We've got to take our performances to the next level to beat these type of teams.

"That's what we're aiming for this week, we've got to be ready to go. It's about attitude now, it's all about performing and executing it now."

Let's go back to the summer of 2023 and Headingley.

Hull KR were very much seen as the upstarts of the day against the might of Wigan.

It was a low-scoring, high-quality affair that was settled by the boot of Brad Schneider with a golden-point drop-goal.

Hello and thanks for joining us for coverage of the first men's Challenge Cup semi-final of the weekend.

You will be forgiven for any sense of deja vu, as this one is set to go off like it was 2023 all over again.

Well, at least Hull KR will want as much as they once again face Wigan Warriors in the last four.

That one was a cup classic.

Will we be treated to a repeat? Let's find out...

Another year.
