Luke O'Donnell says fellow Sydney Roosters recruit Sonny Bill Williams has been training as though he'll play in Thursday's NRL season opener against South Sydney at Allianz Stadium.
An official call is yet to be made on whether Williams makes his tri-colours' debut against the Rabbitohs with the back-rower's build-up to the season restricted by a pectoral muscle injury suffered playing rugby in Japan.
Former NSW and Australian enforcer O'Donnell, who is making his first NRL appearance for the Roosters against Souths, admits he'd be disappointed if Williams didn't play in the match.
"He's trained like he's going to be playing," O'Donnell said on Sunday.
"Team selection and his fitness and that sort of thing is up to the coaches and probably Sonny himself but like I said, he's been training pretty well.
