O'Donnell says SBW has trained well March 3, 2013 - 11:03AM Luke O'Donnell says fellow Sydney Roosters recruit Sonny Bill Williams has trained as though he'll take his place in Thursday's NRL season opener against South Sydney at Allianz Stadium. Williams is in doubt for the match and will have to pass a fitness test later on Sunday to allow him to make his debut for the tri-colours against the Rabbitohs. The star back-rower's build-up to the season was 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. I can only speak from a player's perspective and it would be disappointing not to be running out there with him. But we've all got a job to do so everyone's mind will be 100 per cent on playing well I suppose and not too much on Sonny and whether he's there or not. The 32-year-old O'Donnell signed a one-year deal with the Roosters after being granted a release from English side Huddersfield and is pleased to be home. It's great to be back. The family is happy and I could be happier to be at the Roosters," he said. We've got a good squad here with a good mix of young guys and a bit of experience there too ... it's going to be a good year I think.
