PAUL Wellens welcomes back Jack Welsby to the 21-man squad for the first time since Round 19 against Leigh.

It is a surprise inclusion with the England full back well ahead of schedule after his recovery from a hamstring injury sustained in the opening minutes of that match.

It is the only change with Leon Cowen stepping out of the declaration from the previous round.

Tommy Makinson will serve the second game of his two-match penalty notice.

Coach Paul Wellens said: "Warrington have a number of threats – they are a dangerous team – particularly off the back of ruck speed and that is where the likes of George Williams comes into the game really effectively and with Matt Dufty out they now have Cai Taylor-Wray has been doing a great job there.

"They have strike in the three-quarters, players like Matt Ashton, Toby King, Josh Thewlis and Rodrick Tai playing well – they have strike all over the field and we’ll have to work hard to nullify that."

And when asked what he wants to get from Saturday's game, Wellens replied: "I want to see us improve on last week’s performance.

"There's a lot I liked about it, but not by any stretch of the imagination it was not a brilliant performance – more a kind of get the job done type display.

"I want us to go out there with a competitiveness and resilience and keep showing those qualities but we can be better in a few areas and when we get an opportunity, try and nail them because as I mentioned, big games at the back end of the year, opportunities are few and far between.

"So we need to be clinical there and I'm hoping to make some improvements."
