Scans have revealed that Mat Toshack has a broken leg sustained after a fall in training last weekend and will be out of action for a period of four to six weeks.
Tony Rea has called on Leeds Academy to provide back up in the shape of 20-year-old Jason Netherton who has been included in Saturday's team to play at Halifax.
Netherton, who joined Leeds from West Hull, has come through the Academy system at Headingley alongside the likes of Tommy Gallagher, already on loan with London. Netherton also last year had a five game loan spell at Halifax.
Rea has a number of other players under an injury cloud with Jim Dymock, Rob Purdham, Francis Stephenson, Richard Marshall and Paul Sykes all to face fitness tests on Saturday morning.
Should they all pass these tests, Toshack will be the only change to the side that defeated Castleford two weeks ago.
The team had last weekend off with the postponed round 15 fixture against Huddersfield to be played on Tuesday 22nd July at Griffin Park.
