Sydney Roosters utility Craig Wing should be fit to play in the National Rugby League season-opening encounter with Parramatta after being cleared of a fractured ankle.

Wing badly sprained his ankle playing halfback in his side's 38-0 thrashing of St Helens in Friday's World Club Challenge in Bolton.

X-rays on the ankle, which swelled during the 35-hour flight from Sydney to London, revealed there was no break.

The 23-year-old Wing will miss the trial against Brisbane on March 1 in Toowoomba but is expected to line-up against the Eels at Aussie Stadium on March 14.

"We'll do some more tests during the week, an MRI, just to assess the extent of the ligament damage but at this stage he's cleared of a fracture so that's a good sign," club physiotherapist Craig Walker said.

Coach Ricky Stuart said Luke Phillips (shoulder), Ryan Cross (knee) and Eric Grothe (suspended) will also miss the trial against the Broncos.

The Roosters have now returned home following their successful title challenge in a match played in below-freezing temperatures.

Most of the players spent the day catching up on sleep but Stuart was back at work, preparing his campaign to defend the NRL title in the knowledge that the other 14 teams had the Roosters in their sights.

Asked whether complacency was a danger factor for Sydney this year, Stuart said: "Only time will tell. I'm not expecting it to be (a problem).

"It's not a problem within the coaching staff so I don't think it should be a problem within the players.

"It's just a matter of starting a completely new year. Last year counts for nothing now."

Stuart was naturally ecstatic with the WCC victory but noted it meant little in terms of the NRL season.

"It doesn't guarantee you any success, does it? Just because we won that game or won (the premiership) last year it guarantees us nothing," he said.

"The only thing it guarantees is that every other team is going to prepare and try harder against you."

Skipper Brad Fittler, who received 35 stitches to his head after suffering a nasty cut in the WCC match, added: "Things are always changing but up to this point everyone seems like they're on track, in a good frame of mind and ready to keep learning."

Meanwhile, Bulldogs lock Travis Norton could miss the start of the season after breaking down at training with a hamstring injury.

Coach Steve Folkes confirmed the Queensland State of Origin forward would not be considered for trials against Brisbane on the Gold Coast on Saturday and Manly at Coffs Harbour on February 28.

Folkes added he expected the injury-plagued Norton to be fit for the Bulldogs' season-opener against South Sydney on March 15 but it depended on further medical assessments.

"It's pretty hard to tell how bad it is so we'll have a better idea tomorrow and the next day how long he's going to miss," Folkes said.

The luckless Norton missed nine games with a ruptured biceps last year, suffered a major knee injury in 2001, snapped finger ligaments in 1999 and underwent a shoulder reconstruction at the end of 1998.
