Cooper Cronk will be given up until kick-off to prove himself fit for the NRL grand final – but from the way he’s talking, Roosters staff will have their hands full stopping the former Test pivot.

Scans Sunday revealed that Cronk sustained a severe left rotator cuff injury during his side’s 12-4 win over South Sydney.

Speaking after the match, Roosters coach Trent Robinson said he was confident Cronk would play in his third consecutive decider on Sunday.

The Roosters faces the Storm at 9.20pm on Sunday and you can watch it live on FBC TV.
