Melbourne Storm captain Cameron Smith says fullback Billy Slater is as fit and fast as he has been in recent years and more than capable of returning to the NRL.

Slater has been in full training with the Storm  for months after consecutive seasons were ruined by two bouts of shoulder surgery.

Smith (pictured) says while Slater could be playing this weekend, the club will allow Slater himself to decide when the time is right to resume playing.
