Sunday, July 6

Castleford (12) v Hull KR (9)

Samoan forward Mark Leafa is a surprise inclusion in Castleford's 19-man squad after sitting out the last 11 games with a broken arm and he is set to take the place of Craig Huby, who damaged his shoulder in training. The Tigers also welcome back goalkicking threequarter Kirk Dixon and hooker Scott Moore, who have both missed the last two games.

Hull KR recall Jon Steel in place of England winger Peter Fox, who has been hospitalised this week with an infected knee. Rovers also have a doubt over Ben Cockayne, with Daniel Fitzhenry standing by to take over at full-back, and 21-year-old full-back Lee Gomersall is lined up for his debut.
