FORMER Giants assistant coach Lee St Hilaire has joined engage Super League rivals Wakefield Trinity Wildcats as the No2 to head coach Tony Smith.

St Hilaire, 39, left the Galpharm last week after working on the Giants coaching staff under John Kear, current Leeds boss Tony Smith and Jon Sharp.

St Hilaire has a 20-year association with Huddersfield which included a long stint as a player and also played for Castleford alongside Tony Smith and Hunslet Hawks.

Smith has been on the look-out for an assistant for some time, with club conditioner Anthony Hazeldine helping out the head coach following the departure of Shane McNally.

"Lee has worked under some quality coaches and is an honest kind of bloke," said Smith.

"When I saw last week he'd left Huddersfield I thought I'd better move quickly because I knew he would not be out of a job for long.

"He is a hard-working kind of guy and will be invaluable at Wakefield."

St Hilaire has immediately started working with the squad as they go into a very important tie at home to Hull FC.

GREAT Britain hooker Matt Diskin has agreed a new four-year contract with Leeds Rhinos which will keep him at Headingley until at least the end of the 2010 engage Super League season.

Diskin, 24, whose current contract was due to run out at the end of this campaign, has made more than 100 appearances for the Rhinos since joining them from Dewsbury Moor amateur club in 2001.

"I have played all my rugby here at Leeds and hopefully I would like to remain here for the rest of my career," he said.

Diskin will be in action for Leeds tonight when the Rhinos entertain high-flying Salford City Reds.

But the big game is at Knowsley Road where unbeaten leaders St Helens entertain second-placed Bradford Bulls, who have dropped just one League point this season.

"It's going to be a massive clash in all senses of the word," said St Helens coach Daniel Anderson.
