Wakefield have re-signed goal-kicking scrum-half Danny Brough but winger Peter Fox will join Hull KR next year.
Brough has rejoined the Wildcats on a three-year deal from Castleford.
The 23-year-old Fox, an ex-Leeds Rhinos player who has been virtually ever present this season for Wakefield, has joined Hull KR on a two-year-deal.
"Peter has plenty of speed and he has established himself well within the Super League competition this year," said Hull KR head coach Justin Morgan.
"To have a finisher of his calibre on the end of our back-line will be a huge asset to the team."
