Newcastle Thunder have signed Mitch Clark on loan from Wigan and Kyle Trout from Limoux Grizzlies.
Clark, 28, has been limited to two appearances for Wigan this season, and has previously played in the Championship for Bradford, Featherstone, Halifax and Leigh.
He joined on a three-year deal ahead of the 2020 season, and has moved to the north west on an initial two-week loan deal.
Newcastle director of rugby Denis Betts said: “Mitch will be a good asset for us whilst we have him at the club and I’m looking forward to working with him.”
Meanwhile, former Hull KR forward Trout has signed on a permanent deal until the end of 2022 after a spell in France with Limoux.
The Grizzlies season came to an end last weekend with a play-off defeat to Avignon.
Betts added: “Great chance to sign a seasoned front rower. He has been playing in France which makes him an attractive option for us because he has been playing week in, week out in a very tough position in that league.
“The front row in France is a pretty brutal position to play so he strengthens our front row options, he has a great engine, his work rate is high, he has a good offload, there is a bit of an extra edge to him that we need at this time. He is a very talented player, who is highly thought of and has lots of ability.”
Trout made more than 50 appearances for Dewsbury, and has also turned out for Doncaster, Batley, Featherstone, Whitehaven, Hunslet and Sheffield since making his debut at Wakefield.
