An uncharacteristic mistake by Leeds full-back Zak Hardaker, who fails to grasp a pass from Jamie Peacock and Hull KR have a scrum on half-way.

Leeds go on the attack again, a kick goes up to the right corner, but Rovers winger Josh Mantellato beats Tom Briscoe to the ball.  

Albert Kelly is pulled up for a ball steal and Leeds get a penalty 30 metres out. A huge initial drive from Mitch Garbutt gains valuable ground and Jamie Peacock might be over?! To the video referee, we go.

Leeds twice take it all the way back to Hull KR's 10-metre line but run out of tackles, Rovers twice respond by kicking long late in their own tackle count. Neither side able to create any meaningful opportunities thus far.

A decent, calming first set of six for Hull KR, who are the undoubted underdogs this afternoon. The last thing they would have wanted was to make a silly error in the first couple of minutes, and they haven't.

We're off! Leeds kick us off at Wembley.

As the two sides make their way onto the Wembley turf, Tyrone McCarthy will have thoughts of extending his excellent record in Challenge Cup finals - it currently reads played two, won two. He even scored a try in Warrington's victory over Leeds three years ago.

Today, he is leading out Hull KR as the club play in their first Challenge Cup final for 29 years.

"Hopefully it's a hat-trick of wins," McCarthy told BBC Radio Humberside. "It will be extra special as captain. It's a massive honour for me.

"Personally, it's about getting out there and doing what it takes for us to get the win."

A huge ovation for Lizzie Jones as she enters the field (see 14:56).

The rugby league community is, without doubt, one of the strongest in sport.

Leeds Rhinos captain Kevin Sinfield is switching codes to rugby union at the end of the season and wants to finish on a high - there's a possibility they could win a domestic treble.

The first leg of their bid to win a trio of trophies is today, although the former England skipper is well aware of the threat posed by today's Challenge Cup final opponents.

Sinfield told BBC Radio Leeds: "Hull KR have caused us some problems this year - we've had two really tough games against them.

"This competition can throw up all sorts of shocks, and it's a competition that Hull KR have played their best stuff in. Beating Wigan and Warrington shows that they can be very dangerous."

The two sets of players are ready in the changing rooms and preparing to enter the field.

The new Super 8s format has separated Hull KR and Leeds Rhinos into different divisions for the closing weeks of the 2015 season.

Hull KR finished 10th after 23 Super League games, but sit top of The Qualifiers with three wins from three games and appear certain to retain their top-flight status for 2016.

Leeds have been the dominant force in Super League this term, topping the table for much of the campaign. They have a four-point lead over second-placed Wigan and have won their last six matches in all competitions.
