DARYL Powell has made four changes to his Warrington Wolves squad for Sunday’s Challenge Cup sixth-round tie against Wakefield Trinity.

Skipper Jack Hughes is suspended for one game while full-back Stefan Ratchford will be out for a month with a shoulder injury. Rob Butler and Jack Darbyshire also drop out.

Returning to the squad are prop Robbie Mulhern and winger Josh Charnley, who are available again after a concussion and suspension respectively.

Connor Wrench is also named but is unlikely to play due to an ongoing back injury, while forward Ellis Robson is included having returned from a loan spell at Toulouse Olympique.

Billy Magoulias is expected to make his Wire debut – he was named in last week’s 21-man squad having recovered from ankle surgery but did not make the final 17.

Daryl Clark is named but remains a doubt due to a neck injury.

Wire squad: Matty Ashton, Josh Charnley, Daryl Clark, Jason Clark, Mike Cooper, Ben Currie, Matt Davis, Riley Dean, Oliver Holmes, Toby King, Ellis Longstaff, Billy Magoulias, Peter Mata'utia, Robbie Mulhern, Joe Philbin, Ellis Robson, Josh Thewlis, Danny Walker, Gareth Widdop, George Williams, Connor Wrench
