Five stories to follow in this week’s Challenge Cup

Justin Carney’s second return to The Jungle
If Justin Carney’s second game back at Castleford as a Salford player is anywhere near explosive as his first, then the BBC cameras have picked a belter of a game for Saturday afternoon. Carney was sin-binned after an altercation with Nathan Massey before scoring two tries as the Red Devils picked up a win. If BBC ever felt like there was an appropriate time to introduce ‘Player Cam’, this is surely it.

Can Warrington’s young side beat the giant killers?
The Wolves will send an inexperienced and youthful side to Bower Fold on Saturday to face Oldham – the success story of the last round when they beat Hull Kingston Rovers. With Morgan Smith expected to make his debut and a big shuffle in the side due to injuries, can the Wolves ensure they avoid an upset?

The biggest chance of an upset at The Shay?
Many expect Warrington to get past Oldham and advance to the quarter-finals – but is the round’s biggest chance of an upset in West Yorkshire on Sunday afternoon? Halifax are riding high in the top four in the Championship, and they face a Widnes side who are more than a little bit out-of-sorts. They did manage to beat Rochdale in the last round but that’s their only win in a number of weeks – so can Fax inflict more misery on Denis Betts’ side?

Just how good are Toulouse?
Well, we’ll find that out this weekend. They dumped Leigh Centurions out of the cup in the last round and are still unbeaten in League One, but they face Super League opposition this weekend when they head to West Yorkshire to face Wakefield. The Wildcats are in fine form of late and will fancy a real tilt at the competition in 2016 – not least with the man who guided Hull KR to the final last year, Chris Chester, in charge at Belle Vue. Can they beat the Frenchmen?

How will Hull cope without their powerhouse duo?
Sunday’s marquee game is St Helens’ clash against Hull FC in a meeting of two of the competition’s top five – and it will be interesting to see how the Black and Whites cope without their international stars. Credit must be paid to Hull for releasing Frank Pritchard and Sika Manu to play in this weekend’s international games – the NRL would do well to take a leaf out of their book at times – but will it come back to bite them?
