Castleford will hand a debut to Ben Johnston when they welcome London Broncos to the PROBIZ Coliseum on Sunday afternoon.
The half-back has impressed coach Ian Millward in the Tigers' academy side, while he has also been gaining first-team experience at York City Knights.
Johnston has now been recalled from his dual registration spell at the Championship side and is in a 19-man squad for a game between two teams involved in the battle to avoid the wooden spoon.
The 20-year-old takes the place of Rhys Williams, the winger having returned to Warrington after completing his loan spell at Castleford.
London Broncos currently find themselves propping up the rest in the Super League table, though a win on their travels and a defeat for Widnes at Leeds on Friday night would see them leapfrog the Vikings.
They recorded just their fourth triumph of a difficult campaign last weekend, rallying from a 28-6 deficit against Salford thanks to seven second-half tries.
The capital club are without full-back Michael Robertson, who has an elbow injury, and second rower Will Lovell, who is ill, for the game against the Tigers.
Interim coach Tony Rea has called up Michael Channing and Mike McMeekan, with the latter hoping to make his first-team debut.
Jason Golden is out with a back injury, so Ben Bolger is recalled. Liam Colbon, Matt Cook and Dan Sarginson remain on the sidelines.
Broncos interim head coach Tony Rea told the club's website: "We've had an extended week at training with an extra day in the turnaround which has been helpful.
"We've got some good miles done in preparation for getting to start line."
Castleford: Owen, Youngquest, Griffin, Orr, Emmitt, Huby, Snitch, Jones, Milner, Hudson, Mitchell, Jackson, Millington, Holmes, Massey, Nash, Thompson, Williams, Ellis.
London Broncos: Bailey, Bolger, Bryant, Caro, Channing, Clubb, Dixon, Dorn, Gower, Howell, Kaufusi, Krasniqi, McMeeken, Melling, O'Callaghan, Randall, Rinaldi, Wheeldon, Witt.
