Castleford v Wigan preview
Unbeaten Castleford face the acid test of their improvement with the visit of Super League champions Wigan, according to coach Daryl Powell.
The Tigers are one of the surprise packages of the season so far with three wins out of three but Powell knows the jury is still out on their play-off credentials.
"We've had a great start," said Powell, who succeeded Ian Millward midway through last season.
"It has given us a real good platform but we've some tough challenges to come and we're faced with one of those straight away on Sunday.
"It will give us a real sense of where we're at as a team."
Wigan are unbeaten in their last six visits to Castleford but the Yorkshiremen were 18-4 winners at the DW Stadium last June and Warriors coach Shaun Wane is preparing his side for their biggest test of the domestic season so far.
"They are a good team and it is a difficult place to go," Wane said. "We will need to be much better than we were last week against Wakefield.
"We have won at Castleford a few times in the past few years but I understand this is a challenge for us.
"Daryl is a smart coach, he has got himself a workmanlike team who all play hard for each other and they are throwing a lot at opposition teams.
"I will pick my best team for Sunday because this is our biggest test so far."
Wane recalls full-back Matty Bowen, England winger Josh Charnley, centre Dan Sarginson and forward Eddy Pettybourne and includes veteran prop Jordan James for the first time since he rejoined the club but skipper Sean O'Loughlin misses out with a shoulder injury.
