Larne Patrick and Jack Hughes have agreed one-year loan deals to join Wigan Warriors and Huddersfield Giants respectively.
Hughes has struggled to make an impact in recent times, making the move to the John Smith's Stadium in order to secure some much-needed game time.
Meanwhile, Patrick will move in the opposite direction, linking up with the Super League runners-up until the end of the 2015 campaign.
Wigan general manager Kris Radlinski said: "Jack has found first-team opportunities limited recently with Liam Farrell, John Bateman and Joel Tomkins all cementing their position in the back row.
"As such he recently asked for more first-team rugby, at the same time as Huddersfield asked about his availability. We value Jack and feel he still has more to offer so would only consider the option of him leaving for a specified period in exchange for Larne, a player our coaching staff rate very highly."
Wales international Patrick added: "I am delighted to join Wigan. This is an exciting new challenge and one I am relishing. I have had a great time at Huddersfield and would sincerely like to thank coach Paul Anderson for the way he has helped me.
"I am hopeful that my development continues apace under Shaun Wane, another great British coach and someone I am excited to be working with."
Hughes has made 75 appearances for the Cherry and Whites since making his debut in 2011, while Patrick has featured over 100 times for Huddersfield.
