Catalans Dragons are set to give debuts to Willie Mason and former Huddersfield winger Jodie Broughton against Leeds in Perpignan on Saturday.
Mason, 35, has joined the Dragons on a deal to the end of the season while Broughton made the move to France in the close season but missed the opening two rounds of Super League due to injury.
Going up against Mason could be 21-year-old Jordan Baldwinson, whose only appearances so far this season have been on a dual registration with his old club Featherstone.
Baldwinson, whose eight previous Super League appearances for Leeds and Bradford came either side of a season spent with New Zealand Warriors’ feeder club, takes the place of prop Mitch Garbutt, who begins a two-match ban as a result of his sending-off for punching in last Sunday’s World Club Challenge defeat by North Queensland Cowboys.
Leeds coach Brian McDermott has also called up 19-year-old front row forward Sam Hallas, who has been part of the Rhinos’ academy set-up for the last two years, as the champions go in search of their first win of the season.
