Former Great Britain and England international Jamie Peacock will be the man making Saturday's men's Betfred Challenge Cup draw on BBC Sport, at half-time in the second game between Salford and Castleford (17:30 BST kick-off).

Peacock, who won the cup twice with both Bradford and Leeds to finish his distinguished career with four winners medals, will join Mark Chapman for the grand ceremony.

BBC Sport will have details of the women's draw and a round-up of the action, following the conclusion of their quarter-finals, on Sunday.

If tonight's double-header has whet the appetite for more rugby league then you're in luck, as BBC Sport brings you two ties live on BBC Two tomorrow afternoon.

We get underway with two teams whose mere mention evokes one of the great Challenge Cup finals of our time - Wigan and Hull FC. If Saturday's quarter-final is even half as good a match as the 1985 meeting of the two teams, we're in for a belter.

Then last season's finalists Salford face a Castleford side desperate to send their boss Daryl Powell off with a trophy in 2021. Richard Marshall inherited a squad that came within a point of Leeds in last season's final.

All that kicks off, with a bit of Final Score in the middle, just before 14:00 BST on BBC Sport and on BBC Two.

Catalans boss Steve McNamara

"We stayed in the contest for much of the match. I thought we did tremendously well to stay in the contest.

"We got back in it and we had enough possession in the last 10-12 minutes to stay strong.

"We're extremely disappointed. I don't think we were at our best today. We'll bounce back. We're in reasonable form this season."

Warrington Wolves full-back Greg Inglis told Sky Sports:

"Two years coming out of retirement and Pricey puts me in at full-back. It's what you've got to do in a team.

"Today was a great team effort but from the very start I said I'm here for the experience and I'm here to enjoy it.

"We fell away in the first 10 minutes and in the last 10 minutes but we'll talk about that as a group."

All over at Headingley and Warrington go through to the Challenge Cup semi-finals having overcome Catalans.

Not a classic tie by any means but the Wire get the job done courtesy of a storming start and they never really looked back.

Meanwhile, the Dragons will be frustrated at a lack of chances tonight, with Warrington worthy of their win.

Two minutes to go now with this game, typically, winding down as the sun sets at Headingley.

Warrington are coasting through to the semi-finals in the first of this weekend's Challenge Cup fixtures.

Samisoni Langi looks to work on to Joel Tomkins' offload right in the corner as Catalans threaten a late try.

He knocks on as he can't keep hold of the ball but the Dragons are given a reprise as Jake Mamo interfered in the process.

Another set of six follows but Warrington hold firm and Catalans can't find a way through before the turnover.

Mike McMeeken looks to get away to touch down his second for Catalans but he's well held up by Toby King and Jordan Widdop.

Referee Liam Moore sends it upstairs but it's inconclusive and, correctly, the try isn't given.

Catalans will want to get away quickly as they try to find the points they need as time ticks down.

We're into the final 10 minutes now and Warrington look to be holding firm so far.

Catalans really have been undone by their slow start, here, but have very rarely looked up for the fight even in the second half.

Warrington's Gareth Widdop goes for the two as they win a penalty just past halfway but he misses his attempt.

Fortunate for Catalans who are just about still in this game, but desperately need another try soon.

Josh Thewlis is having a cracker of a match as he springboards off his try-saving interception to race upfield for Warrington.

He picks the ball up in his own half and races past a number of Catalans players before he's finally brought down.

A lot of knocking on going on in this match.

Ben Garcia is the latest Catalans player to spill the ball under next to no pressure.

Fortunately for the Dragons, they win a set of six in a dangerous position but Warrington win it back through some good work from Josh Thewlis to intercept in the corner.

Catalans come close to getting off the mark here but Josh Charnley puts in a try-saving tackle on Dean Whare.

It's just not happening for the Dragons tonight.

Blimey. Warrington are piling onto Catalans now and they win a set restart within touching distance of another try.

However Blake Austin spills the ball and knocks on no sooner does a promising break starts.
