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.
The Tigers played the second half with just two men on the bench after Josh Aloiai failed a concussion test.
As well, prop Sauaso Sue was an 11th hour withdrawal after injuring his ribs in the warm up.The defeat was the Tigers' eighth in nine games and reapplied the pressure to coach Jason Taylor.
Tigers halfback Luke Brooks also came in for criticism from legends Peter Sterling and Andrew Johns in television commentary after his light involvement.
Winger Justin Hunt will come under the scrutiny of the match review committee after an ugly coathanger tackle on Dogs halfback Moses Mbye.
The Bulldogs shot out an 18-0 lead before returning Tigers skipper Aaron Woods put Mbye through a hole to score in the corner to give the home side a sniff.
But when Josh Morris scored in the shadows of the break and Curtis Rona bagged his double 12 minutes after the resumption, the match was effectively over.
