Hull FC pair Dean Hadley and Jez Litten have both joined cross city rivals Hull KR on initial loan deals.
Once these deals come to an end, they will both sign deals until the end of 2022.
Hadley plays either in the second row or at hooker and has made 88 appearances since coming through the Black snd Whites academy set up, scoring ten tries.
As well as this, he has had three spells at Doncaster, scoring one try in six apperances for the South Yorkshire club, as well as other loan spells at York City Knights and Wakefield Trinity.
It was at Wakefield where he was his most successful as he scored twice in 22 matches.
Litten can also play at hooker or at halfback and has scored one try in 18 matches since coming through the Black and Whites academy in 2017.
Like Hadley, Litten has also had three spells at Doncaster, where he has scored seven tries in 18 games.
Both could be in line to make their debuts as Rovers host Castleford Tigers next Sunday.
