You can't take your eyes off this one. Is the sun beginning to set on Hull KR's 2019 Challenge Cup campaign?

Warrington, who had two players sin binned in that first half, lead this one at the break.

Tom Lineham's valiantly making an impact for a now 12-man Warrington, barging his way into player after player.

The Wire's set of six results in a Blake Austin kick and Hull KR are pegged back into their own half.

Hull KR are getting desperate to get their first points on the board and there's a succession of kicks as they look to break through a resilient Warrington defence.

Weller Hauraki is the latest to try his luck but the Wire win the ball back and another Rovers attack is neutralised.

Meanwhile, Tom Lineham prepares to make his way back onto the field for Warrington.

We've gone to the video referee after Danny Addy grounds the ball over the line for Hull KR.

However there's a knock-on in the build up and Robert Hicks, who initially signalled no try, says nothing doing and play continues.

A let off for Warrington. That's not gone down well with the home crowd.

Declan Patton is the latest Warrington player to receive a yellow card for an offisde tackle.

Meanwhile Hull KR try a cross-field high kick to try and find a way through to score and it's too high for Ben Crooks to work on to.

The play is STILL in Warrington's 10 only now the 11-man visitors have possession.

Somehow, Hull KR haven't scored a try despite having an extra man and a sustained amount of pressure.

Countless sets of sixes have been and gone but Warrington are holding firm and won't let the hosts through.

Brilliant tackle!

George Lawler picks up the ball in the corner and should surely score for Hull KR but he's held up after crossing the line by a stunning Ben Currie intervention, who wedges his body between the ground and the ball.

Lovely stuff from Warrington.

Danny McGuire goes down from a low Warrington tackle and there's some afters from Chris Hill which provokes a stern talking to from referee Robert Hicks.

Hull KR still have four tackles and they're camped in Warrington's 10 but Ben Crooks is held up.

In the mean time, Tom Lineham goes in late on Jimmy Keinhorst in an off-the-ball challenge and goes into the bin for 10 minutes.

Josh Drinkwater thumps a left-footed grubber kick and finds touch close to the Warrington in-goal area.

From the scrum that follows, Warrington begin another attack but Ben Currie fumbles the ball, much to the delight of the hosts.

The ball bounces awkwardly upfield for Warrington's Jake Mamo and his teammate Josh Charnley works his way onto it but he's held up well by the hosts.

This an entertaining game already. Finely poised as it stands.

Hull KR have started this game strongly and are valiantly trying to find a pathway through to the Warrington half of the field.

The hosts almost reach Warrington's 10m line before the turnover and the visitors struggle to make it past halfway with their set of six.

Great start for Hull KR.

The players have made their way out at Craven Park and Hull KR get us under way.

Who's going to bag themselves a Challenge Cup semi-final place?
