Featherstone head coach Ryan Carr will combine his role with a job on the backroom team at Leeds.
Carr, 31, joined Rovers at the start of the season and will assist Richard Agar at Headingley.
He said: “I am excited about the opportunity with the Rhinos. I know a number of the squad because of the dual registration arrangement we have between Featherstone and Leeds and undoubtedly there is a lot of talent here. I am looking forward to working with the coaching team and the players and helping out in any way I can.”
Carr was forced to retire from playing in his early 20s, and has since been part of the coaching team at South Sydney Rabbitohs and Cronulla Sharks.
Agar said: “We are delighted that Ryan has accepted our invitation to be part of our back room team. We are in a fortunate position to have a fairly healthy first team squad at the moment with over 30 players training each day.
“It was felt necessary to bring in extra resource to make sure every player is getting the attention they need to continue to move our game forward. That is particularly true for our talented young players, many of whom have worked with Ryan at Featherstone and who have had lots of positive things to say about him.
“Ryan’s primary focus will remain with Featherstone however he will be part of our set up at the start of the week when our workload is particularly high. He has already made a good impression.”
