Wales forward Ben Evans has been reunited with twin brother Rhys at Championship club Bradford.
Ben will also be reunited with Wales head coach John Kear, the veteran Bulls boss.
He said: “Coming over with Rhys today has brought back some good memories from the last time I was here and I am looking forward to getting started.
“I will bring some experience to the side and try help the boys by doing what I can do help out with what I know.
“I have worked with John for the last couple of years now. I know him well on and off the field and I am looking forward to working with him and the strong squad he has built.
“Hopefully I can start training this week and do what I can to earn a place in the squad for Sheffield a week on Sunday.”
Bradford made the move for Evans after losing Sam Hallas with a fractured jaw in Sunday’s Challenge Cup defeat at Featherstone.
Kear said: “I am really pleased. Fortunately we were in the right place at the right time with Ben and, with Sam’s injury, we moved very quickly.
“Ben is a very good signing and a statement of intent.”
