Bradford Bulls have signed forwards Jordan Baldwinson and Mason Tonks from NRL side New Zealand Warriors until the end of the season, when they will return to Leeds Rhinos.
The pair, both 19, joined the Warriors from Rhinos for the start of this year.
Both are likely to make their first appearance for the Bulls in the trip to Catalan Dragons on 24 May.
"This is a fantastic opportunity for both Jordan and Mason," coach Francis Cummins said.
Leeds head coach Brian McDermott added: "It is always good to be bringing back two of our own players, who have come through our academy structure and whom we have invested a lot of time in early in their careers.
"I am sure they will have learnt a lot from their experience with a NRL club and will be looking to stake their claims for next season when they get back."
