Hull KR have second rower Con Mika back from injury for Sunday's Super League visit of second-placed Warrington.
Mika has recovered from the chest infection that forced him to miss the derby win over Hull.
Rovers head into the contest boosted by that terrific win over their fiercest rivals, but coach Craig Sandercock knows it will be a big ask to back-up against the Wolves.
"It doesn't come any tougher than a game against Warrington," he told the club's website. "They're second on the ladder, put 68 points on Widnes last weekend and have class players throughout their team.
"They were a little bit understrength last weekend and were missing a few key players who will be back this week. We picked up on a couple of little things but really it's more about our own performance and trying to come up with our best against very good opposition.
"When you're playing a side with as much class as Warrington you need to be at your best and all 17 boys who play for us this weekend need to be at their best. If we do that, then I'm quietly confident we'll be in a position where we could sneak a win."
Warrington coach Tony Smith has recalled some of his big guns for the trip to Humberside.
Full-back Brett Hodgson, centre Chris Bridge, second rower Ben Westwood and hooker Micky Higham return after sitting out the 68-4 win over Widnes in Manchester.
Youngsters Ben Currie and Brad Dwyer are among those making way, while there is no place for Paul Wood in the 19-man squad.
Hull KR squad: Clinton, Dobson, Galea, Green, Hall, D Hodgson, J Hodgson, Horne, Latus, Lovegrove, McDonnell, Mika, Murrell, O'Hara, Paea, Taylor, Watts, Welham, Withers.
Warrington squad: Atkins, Blythe, Bridge, Briers, Carvell, Cooper, Grix, Harrison, Higham, Hill, Hodgson, McCarthy, Monaghan, Morley, O'Brien, Ratchford, Riley, Waterhouse, Westwood.
