In a battle under the rim during the third quarter, Cleveland's Tristan Thompson fell on Bogut's leg, hyper-extending his left knee and while reports are still preliminary, the Warriors have diagnosed it as a sprained left knee.

Bogut will have scans overnight but a sprain is a positive outcome for the Aussie who has already suffered his fair share of career-threatening injuries.

Needing a victory to keep the series alive, Cleveland received outstanding performances from LeBron James and Kyrie Irving to help keep team mate Matthew Dellavedova's dream of a Championship alive but Golden State need to only win one of the next two games to clinch back-to-back titles.

The entire Basketball Australia will keep their fingers crossed for Bogut overnight as he aims to return to the court for not only the NBA Finals later this week but the Farewell Series in Melbourne in July and Rio in August.
