Rhinos are understood to have handed over separate six-figure fees for the pair in their biggest transfer coup for more than a quarter of a century.
Here’s the Yorkshire Evening Post’s choice of Leeds’ 20 highest-profile signings from fellow Super League clubs since the competition began in 1996.
7. Jamie Peacock (2006)
Great Britain captain and a former Man of Steel when he moved from Bradford Bulls, Peacock is arguably the finest signing Leeds have made from another English club, certainly in the Super League era. Photo: Dan Oxtoby
8. Zak Hardaker (2011)
Still a relative rookie when Rhinos signed him from second-tier Featherstone Rovers, Hardaker won a Grand Final at the end of his first season and was Man of Steel four years after his Leeds debut. Photo: Steve Riding
9. Joel Moon (2013)
Rhinos paid Salford an undisclosed fee for the unsettled Australian centre. Their coach Phil Veivers claimed: “Joel made it pretty clear he wanted a move. He said he was homesick, I haven’t checked the map, but I presume Leeds must be closer to Sydney than Salford is.” Photo: Steve Riding
