Hull KR prop Ryan O'Hara could miss start of season
Hull KR prop Ryan O'Hara could miss the start of the 2013 Super League season after undergoing Achilles surgery.
The 32-year-old, who made 15 appearances in the league last season, struggled with the injury towards the end of last season.
Robins boss Craig Sandercock told the club website: "If he had kept playing or training it could have gone so it's why we decided he should have surgery.
"We are racing against time for him to be fit for round one."
