Adrian Morley is back for high-flying Warrington in Friday's Super League clash against Hull FC at the Halliwell Jones Stadium.
Veteran forward Morley has missed the last 11 league matches after being sidelined since round three with a back injury.
Warrington are currently third in the table and success over the Black and Whites could see the Wolves leapfrog Huddersfield Giants into second place.
However, Wolves head coach Tony Smith knows Hull have the quality, especially with Gareth Ellis back in their ranks, to cause an upset on their travels.
"Hull are finding some form and have shown some good displays in recent times," Smith told the club's official website.
"They've got their captain back in Gareth Ellis who is a quality player with some fantastic experience behind him.
"He has certainly bolstered their squad but they've got a number of strengths across the park. It will be a good test for us and a good contest out there on Friday night."
Hull FC coach Peter Gentle has made one change to his squad for the trip across the M62 to Warrington.
Youngster Jamie Shaul has been drafted into their 19-man squad in place of prop Liam Watts, who picked up a leg injury in the victory over Wakefield Trinity Wildcats last time out.
Winger Jason Crookes will also be involved while front-rower Josh Bowden is pushing for a place in the pack after retaining his place in Gentle's squad.
Warrington: Atkins, Briers, Carvell, Cooper, Currie, Grix, Higham, Hill, J. Monaghan, M. Monaghan, Morley, Myler, Ratchford, C. Riley, G. Riley, Waterhouse, Westwood, Williams, Wood.
Hull FC: Bowden, T. Briscoe, Crooks, Crookes, Ellis, Green, Holdsworth, Heremaia, Horne, Houghton, Johnson, Lineham, Lynch, McDonnell, O'Meley, Pitts, Shaul, Whiting, Yeaman.
