Coach Mark Aston must juggle two from three for the key role of hooker at Sheffield Eagles.
Gareth Owen, on loan for Salford Red Devils, started in the win at Keighley with James Davey on the bench. It left Scottish international Andrew Henderson, who started the season at nine, sitting out a rare game.
“We have three good number nines, three of the best in the competition and they can’t all play” said Aston. “We want competition for places. Andrew Henderson was left out at Keighley and we know that’s hard, and it was a tough decision.”
Owen and Davey both had good spells in the 42-24 win at Keighley. That will make a decision harder when Aston selects the squad for Saturday’s fourth round Challenge Cup game against London Skolars at Owlerton.
Henderson said: “In the hooking role we look healthy. When I do retire these guys can certainly keep take us forward.”
