Brent Webb is one of three players to have joined Leeds' injury list
Super League champions Leeds have been hit by a triple injury blow after Kylie Leuluai, Matt Diskin and Brent Webb were all ruled out for up to six weeks.
Leuluai and Webb have ankle ligament damage, while Diskin has suffered a tear to his groin.
But the Rhinos do have better news of three of their injured players.
Ali Lauitiiti, Luke Burgess and scrum-half Rob Burrow should all be back in the next few weeks, says Leeds' head of physiotherapy services Meirion Jones.
"Ali Lauitiiti has returned to running work following his calf tear," he told the club's website.
"Rob Burrow has returned to running and agility work, while Luke Burgess has also returned to running work.
"All three are in the process of building up their match fitness.
"But both Kylie and Brent will need a rehab period of 4-6 weeks to recover and Matt Diskin will be unavailable for selection for 4-6 weeks."
That would make all three struggling to be fit in time for the Challenge Cup semi-final against St Helens on 7 August.
