WOLVES will have some of their big guns back in the groove for Sunday's Powergen Challenge Cup semi-finals clash with Wigan at the Halton Stadium, kick-off 3.45pm.

Wolves' head coach Paul Cullen said that 'four or five' of the star turns which did not feature against Wigan on Easter Monday will play this time.

Skipper Lee Briers is confident of returning, as are centre Brent Grose, utility back Graham Appo, back rower Ian Sibbit and props Chris Leikvoll and Paul Wood.

Cullen said: "We will have a fit, sharp, focused and determined squad of 17 players and they will be buoyed by the performance that the team put in on Easter Monday."

Briers has not played since the quarter-finals win at Whitehaven on March 28 due to a 'fingers bent backwards' injury.

As for the others, Grose twisted an ankle against Widnes on Good Friday, Appo's niggling hamstring tightened in his last outing at London on April 4, Leikvoll has not played since March 7 while Sibbit and Paul Wood missed Monday's game with minor knocks.

Warriors coach Mike Gregory, who was captain of the last Warrington team that played in a Challenge Cup final in 1990, has overseas ace Adrian Lam back on board after injury.

Hooker Terry Newton is due to return to the side but Great Britain backs Brian Carney and David Hodgson are sidelined.

Wigan skipper Andy Farrell's availability depends on the outcome of his RFL disciplinary hearing last night, Wednesday.

Star Australian winger Brett Dallas is a doubt after being knocked out in a challenge with Wolves' Richard Varkulis on Monday.

Wolves are going into the game highly encouraged by their display at Wigan.

Cullen said: "We were a fraction short in our Easter Monday game and that's all it is. The confidence that our players can take from their performance is invaluable. The shape and structure that we operated will stand us in great stead."
