A Warriors team without either Johnson or Thomas Leuluai would be a unusual sight. Leuluai didn't miss a single match last season while Johnson has also been remarkably durable. He missed just two games during his first full NRL season in 2012 and hasn't been absent on game day since.
The current situation also puts the Warriors' halves depth under the spotlight. Lolohea is a player of immense promise but he has yet to play a first grade game.
Chad Townsend has improved steadily this season but is probably not ready to run the team on his own. Johnson has also hit rare form with his goal kicking in recent weeks, though Townsend would also be a capable backup.
Meanwhile, there has been some positive news for Leuluai.
He had an operation late last week to remove a small "sports-hernia" as he continues his recovery from a groin injury.
It is not expected to be the sole cause of his osteitis pubis condition but is understood to be a contributing factor. McFadden now hopes Leuluai will be back in "three or four weeks".
