Hull owner Adam Pearson has revealed the signing of Castleford centre Jordan Thompson.
Thompson, 22, came through the youth system at Castleford, making his debut against St Helens back in 2009.
Pearson now plans to add two forwards and another outside back to Peter Gentle’s squad, but is prepared to wait until the end of the World Cup to make decisions.
“Our plan is to bring three more players in, an outside back, front rower and probably a back rower as well.
“We will keep our powder dry on the forwards until the World Cup as we feel to have no quota or cap space available when so much new talent will be on show would be a mistake.”
Thompson has scored nine tries in 25 appearances for the Tigers this season.
