In a massive boost for the Canberra Raiders, Josh Papali'i is confident he'll be fit to face the Newcastle Knights on Sunday.
The Green Machine enforcer told fellow prop Emre Guler he would likely return from his calf injury to play his first game of the NRL season.
Papali'i was out doing extra fitness work on Monday morning, having been struck down with a calf strain on the eve of the season.
