Match Preview

Rangi backed to keep up the Chase

Danny Orr is confident his old half-back partner Rangi Chase will maintain his form and focus despite the uncertainty over his future as Castleford prepare to take on Leeds in the Tetley's Challenge Cup.

Chase looks certain to return to St George Illawarra, who are also being linked with his England team-mate Gareth Widdop, and Castleford chief executive Steve Gill says the club "will deal with the matter" after the fourth-round tie at Headingley.

Orr, who has stepped in as caretaker-coach following the departure of Ian Millward, claims to be in the dark over the England international's plans but admits he holds the key to the Tigers' hopes of springing a cup upset.

Chase, the 2011 Man of Steel, produced a man-of-the-match display in Castleford's much-needed win over Widnes last Saturday in what might prove to have been his final Super League appearance and Orr is expecting another big performance from him on Friday.

"Could it be his last game, potentially yeah," Orr said. "I honestly have no idea.

"All I know is that Rangi is 100% committed to the club and he'll be playing tomorrow night.

"With Rangi, no matter where he goes there is always speculation and rumour and there's always people either patting him on the back or having a go at him.

"He's accustomed to all that, he's used to all the pressures that come with being Rangi Chase.

"He's a key player for us, everybody knows that. He's a big part of what we're trying to achieve here and for us to do well we need Rangi to do well. He's aware of that."

Orr is able to recall Australian winger Justin Carney from his two-match ban while second rower Lee Gilmour, who won the cup five times with Bradford and St Helens, is back from injury.

Leeds, runners-up at Wembley for the last three years, are close to full strength as they look to maintain the form that has brought them a five-match unbeaten run in Super League.

Orr says his team's morale has been lifted by their first win in eight matches and believes they will also take confidence from a 14-12 win over the Rhinos in February.

"It's a totally different competition and a different venue but we've beaten them once so there's no reason why we can't beat them again," he said.

"It's going to be very tough but I've been in Cas teams that have gone to Headingley and won. It's not mission impossible.

"Last week's win has lifted spirits. They're happier, you can see that in the way they've trained this week. It's raised morale within the group."
