Crusaders forward Ryan O'Hara and Huddersfield Giants' Graeme Horne have both joined Hull KR, the Super League club confirmed on Saturday. Thirty-year-old O'Hara and Horne, 26, both signed two-year contracts with the Robins, who do not have a coach for next season following the recent confirmation that Justin Morgan would leave the club at the end of the season. O'Hara, a former New South Wales representative, joins the club as a non-quota player following a directive from the Rugby Football League, designed to find new homes for the players affected by the collapse of the Crusaders. "It has been a bit of a rollercoaster for a few weeks and at one point it looked like I'd be going home for good," O'Hara said. "But with the RFL ruling on quota spots, I had a few offers from clubs but, with knowing a few of the guys who play here already, coming to Hull KR was a good fit for me." Horne's move sees him return to the city where he first emerged in the game, albeit across the river with Hull FC. The club also recently signed Huddersfield winger David Hodgson.
