Caretaker coach Danny Orr admits he has "no idea" if Friday's Tetley's Challenge Cup clash against Leeds will be Rangi Chase's last appearance in a Castleford shirt.
Half-back Chase has been heavily linked with a move back to St George Illawarra, with Tigers chief executive Steve Gill saying the club "will deal with the matter" after the fourth-round tie at Headingley.
Yet despite all the speculation about his future, the England international is being backed by Orr to produce another inspirational display for Cas.
He was at his influential best against Widnes last time out, helping his team clinch their first victory in eight matches. It was only the Tigers' second win of the campaign, the other coming at the expense of Leeds back in February.
"Could it be his last game, potentially yeah," Orr - who has taken over on a temporary basis following the departure of Ian Millward - 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."
Chase, the 2011 Man of Steel, was linked with a move back to the NRL last season, while a potential switch to Super League rivals Hull FC fell through due to visa issues.
