Sheffield have signed Connor Bower and Rob Worrincy ahead of the 2020 season.
Centre Bower joins the Eagles on a two-year deal from Doncaster, where he scored 14 tries in 28 appearances last season.
Bower said: “For me, I’ve always aspired to get to this level. I’m finally happy that it has come about.
“To progress as a player is something I want to do and I’m happy to say I’ll be here for the next two years as it’s comfortable for myself so I can knuckle down and hopefully we can have a couple of successful seasons.”
Winger Worrincy arrives from Dewsbury on a one-year contract. He will play in his fourth stint with Sheffield in 2020.
Worrincy added: “Coming back here to Sheffield, with the aspirations they have, is something I couldn’t really pass on.
“I am coming to the twilight of my career but I still have something to offer and I feel here at the Eagles, it’s an opportunity for me to contribute to hopefully another successful season.”
