Wests Tigers hooker Robbie Farah has been taken to hospital with a worrying head injury in his side's 36-4 NRL loss to Canterbury on Sunday.
Farah was knocked out after he collided with the hip of Josh Reynolds as the Bulldogs playmaker put in a kick during the first half in front of 20,936 at ANZ Stadium.
After being stretchered from the grounds, he was taken to hospital as a precaution however his involvement in next month's State of Origin series opener is in jeopardy.
With NSW to name their team for game one after next weekend's round, Blues coach Laurie Daley will be sweating on Farah's fitness but has in-form Cronulla rake Michael Ennis waiting in the wings.
After being inconsistent during the opening rounds, the Bulldogs looked well organised with their big men rolling over the top of the Tigers.
