Hanson, 21, is a product of the Eagles’ youth system, and played in the Championship Grand Final against Featherstone in 2011.
He played in Sheffield’s opening Championship game against Barrow, and last week scored five tries for the academy under 20s side against Oldham.
Coach Mark Aston said: “Corey has been one of the prime examples of our great youth development and performance pathway.”
“After a difficult period with injury it’s taken time for him to get back to the level he knows he’s capable of.
“He’s had an excellent off season, fought his way back into the first team and thoroughly deserved his starting place against Barrow.
“We now have a larger and stronger squad than at the start of the year with competition across the team.
“This has meant Corey has played with the Academy but this move will allow him to play at a higher level with hopefully more consistent game time allowing him a greater chance to fight his way back into the first team.
“He fully remains part of our plans and the move is beneficial for his development and suits all parties.”
