In a massive blow to Wests Tigers' finals hopes, one of Australia's top sports doctors admits Robbie Farah has likely played his last NRL game.

And his teammates also don't expect to see the veteran No.9 in a Tigers jersey again.

Having already announced his retirement at the end of the year, Farah is sweating on any positive news from specialists after initial scans confirmed he had a crack at the top of his right tibia.

Farah bravely played on for 10 minutes against Canterbury on Saturday night, where he put in a kick and even tried to score from dummy half before he succumbed to the pain.
