Bradford Bulls forwards Tom Olbison and Adam Sidlow have signed new contracts after pledging their loyalty to the relegated First Utility Super League club.
Second-rower Olbison, 23, who is a product of the Bulls' academy, has agreed a new two-year deal while former Salford Red Devils prop Sidlow, 26, has signed a 12-month contract covering the 2015 Kingstone Press Championship season.
They have followed team-mates Dale Ferguson and Lee Gaskell in committing their futures to the club, who have also signed Jake Mullaney and Dan Fleming from Salford and Castleford Tigers respectively for 2015.
Bradford coach James Lowes said: "I think it is fair to say things are very much coming together. We have had plans in place for some time and are now executing them.
"Some notable names have already been signed and there will be plenty more to come, as negotiations gradually come to a close.
"Both Tom and Adam will prove key for us next year. They are further pieces to the puzzle and I am really pleased to see them staying put.
"Tom is a fantastic young player, with a terrific attitude and, because of that, I feel sure he will fulfil his potential in the game.
"Adam gets through a huge amount of work and will certainly compliment the more explosive players we are looking to bring to the club.
"He is someone who if asked to do 80 minutes will do so. He is that sort of bloke.
"These signings are further proof of the board's desire to see us make an immediate return to Super League for 2016."
