World club champions Bradford Bulls have signed forwards Ryan Hudson and Andy Lynch from Castleford Tigers.
Hudson has signed for three years
Prop Lynch, who is part of the England squad, has signed a two-year deal with the Bulls, who lost the Super League Grand Final to Leeds last week.
Hudson, who can play in either the back row or at hooker, has signed a three-year deal with the Bulls
"Both players will be great additions to our squad for the next few years," said Bulls coach Brian Noble.
"They are both young players but with a wealth of experience behind them.
"I think they will develop in our environment and will quickly establish themselves as favourites with the Bulls supporters for many years to come."
