Bradford Bulls prop Rob Parker is to leave the newly-crowned Super League champions to join Warrington. Parker, 24, has made 104 appearances since his debut in 2000, scoring 17 tries, but has been released from the final year of his contract.
Bulls chairman Chris Caisley said: "Rob has been outstanding for the club both on and off the field since joining us.
"It is purely a business decision based on salary cap implications. I wish him every success in the future."
