Cronk's herculean effort to play through the grand final with a fractured left scapula will go down in premiership folklore, and he was required to have a plate inserted after the match.

Off-contract at the end of 2019, the Roosters confirmed on Tuesday Cronk will have no issue running out against South Sydney in the opening round at the SCG.

Former Rabbitoh Angus Crichton will also be available after undergoing surgery on his right shoulder to fix an ongoing issue.

Fellow forward Zane Tetevano was also injured in the grand final win over Melbourne, but will recover from his ruptured bicep in time for round one in March.

But the news isn't so good for newcomer Ryan Hall, who is still expected to miss the start of the campaign after tearing his anterior cruciate ligament while playing for Wigan last Super League season.
