Castleford say they have rejected an offer from former boss Stuart Raper to assist caretaker coach Danny Orr until the end of the season.
Raper, who coached the Tigers from 1997 to 2001, had contacted the club to offer his services in the interim while they seek a permanent successor to Ian Millward.
However, in a statement on their official website, club chief executive Steve Gill is quoted as saying: "We thought long and hard about Stuart Raper's offer to work with Danny Orr until the end of the season, however we have decided not to go down that route.
"I think that the financial outlay that would have been required to bring Stuart over could be used more wisely on a long-term appointment."
Gill also spoke positively about the club's search for a new coach.
"We're progressing with our search," he added. "We have had a total of 10 applicants to date and we are busy assessing and meeting with them."
Castleford are currently 13th in Super League, level on points with bottom club Salford.
Raper enjoyed a successful time as Tigers coach, leading them to within 80 minutes of the 1999 Grand Final before they were eliminated in the final knock-out round by St Helens.
After leaving Castleford, Raper went on to take Wigan to Challenge Cup glory in 2002, before returning to Sydney to take charge of his former club Cronulla.
He has been without a club since 2006.
