Wolves ready for Saints clash
Warrington will be aiming to reach their first-ever Grand Final on Saturday when they battle St Helens at Langtree Park (kick-off 6.15pm).
The Wolves surrendered home advantage after losing 28-6 to Saints in the opening round before progressing last weekend with a 24-12 over Hull FC.
Australian back rower Chris Flannery returns to Saints' 19-man squad after missing the last three weeks, but England centre Michael Shenton is ruled out.
Ade Gardner is included, but coach Mike Rush is unlikely to much in the way of adjustment to the side that is aiming to reach a seventh consecutive Grand Final.
For Warrington Man of Steel nominee Ben Westwood and Garreth Carvell are both named Tony Smith's squad, with Chris Bridge and David Solomona missing from the 19 named last week against the Black and Whites.
"We know what to expect and defence is a bit of an attitude," Saints coach Mike Rush commented in the Liverpool Echo.
"You've got to turn up for one another and you've got to work really hard even when the ball's gone past you, or it's not in your area, because there's always a chance it can come back.
"The players are well aware of that, but I'm sure Warrington will want to throw more at us and take a few more risks knowing it's knockout football."
Warrington coach Tony Smith said: "We'd like to maintain this record at Langtree Park if we could but it's about how you perform on the evening. It's a great place to play at and there'll be a great atmosphere with two very good teams capable of playing some very good Rugby League," he told the club's official website.
"The team that performs the best on the night will take the spoils. There are terrific match-ups across the park and we're both capable of producing something special. It has the makings of good competitive game and one worthy of this time of year."
