Leeds are sweating on the fitness of their numbers eight and 10, Mikolaj Oledzki and Tom Holroyd, who both missed Thursday’s Betfred Super League round two defeat at Hull KR. Two more props could face a disciplinary charge and another is not yet available for selection following a 13-month injury layoff. Rhinos also have at least two backs on the casualty list, with a concern over another. Here’s who’s in doubt or definitely ruled out, plus potential return dates.

7. James McDonnell
Hasn't played since Boxing Day, because of a hamstring issue picked up in training. Was named in the squad for the game at Hull KR, but didn’t make the 17. Photo: Steve Riding

8. Derrell Olpherts
The winger played in three of Rhinos’ pre-season games, but missed round one because of a hip problem. He is expected to the visit of Catalans, but could be available for the trip to leigh Leopards in round four. Photo: Steve Riding

9. Morgan Gannon
Gannon suffered successive concussions in pre-season, against Wakefield Trinity and Hull KR, after similar issues in the previous two seasons. Despite no symptoms, he has been stood down from playing and contact training for three months as a precaution so is unlikely to be back in the side before June. Photo: Allan McKenzie/SWpix.com

10. Kieran Hudson
The rookie prop tore an Achilles in pre-season last year, when he was a Castleford Tigers player. He made his comeback for a second-string Leeds side against Hunslet earlier this month, but is not yet being considered for first team selection. Photo: Jonathan Gawthorpe

11. James Donaldson
The substitute forward was sin-binned against Hull KR for a high tackle. The match review panel will study the incident on Monday. Photo: Jonathan Gawthorpe

12. Max Simpson
