New Zealand star Sonny Bill Williams has set his sights on making his comeback from injury in the World Club Challenge against Leeds.

The 19-year-old Canterbury Bulldogs loose forward has been ruled out of Saturday's Gillette Tri-Nations clash with Great Britain in Hull with a shoulder injury.

That means his next match will be back in England on February 4 in the Carnegie World Club Challenge at Elland Road.

Williams, whose injury has been diagnosed as a torn muscle, is confident of being fit to face the Rhinos and insists the Australian champions will be taking the match seriously.

"I'll need a bit of rehab but I should be okay," he told a news conference at Elland Road to announce the Rugby Football League's five-figure sponsorship deal with Leeds Metropolitan University's Carnegie sports faculty.

"The boys started training this week. There are 20 spots up for grabs and everybody is putting their hands up. It's not just another game," Williams added.

"A lot of clubs have come over in the past and not taken it too seriously but I know we'll be fully concentrating on it.

"We'll be fielding our best side possible. It would be a great start to the 2005 season if we could get a win."

The match will also have special significance for Leeds captain Kevin Sinfield, who says he is raring to go after being omitted from the Great Britain squad for the Tri-Nations Series.

"It's been a focus for me," said Sinfield.

"I've done a lot of thinking and I'm really looking forward to this match. I'm more hungry and motivated than I've ever been."

The League are hopeful of filling Elland Road for the second time in three months after it was confirmed that the Tri-Nations final on Saturday week is a 39,000 sell-out.

"Interest has lifted tremendously since the end of the season and our season-ticket sales are double what they were this time last year," said Leeds marketing chief Rob Oates.
