The 26-year-old, who can play hooker, centre or loose forward, has moved to Wakefield after seven seasons with the Black & Whites where he made 115 appearances, touching down 11 times in the process.
Wildcats Chairman Andrew Glover stated his delight at having the versatile player on board “Danny is a great signing for us. Richard has seen his skill and work ethic first hand whilst at Hull and speaks very highly of the utility player.”
“His ability to play at a number of positions will further strengthen the squad next year and his big game experience will stand him in great stead.”
Washbrook declared how he was looking forward to joining up with Wakefield and working alongside his former boss Richard Agar.
“At this stage in my career, I felt the time was right for a change and a new challenge for to kick me into gear. I had a number of opportunities that presented themselves, but I am delighted to be joining a club like Wakefield and continuing to work with Richard.
“He is looking to build a competitive squad, everyone at the club is passionate about what they do and that is something I am looking forward to being part of. Like at Hull, it is another rugby league hotbed and the fans are mad about the club and the sport and I think that sort of atmosphere and environment would excite any player. I can’t wait!”
