Leeds seething as prop Kylie Leuluai is ruled out for weeks

Leeds will be without their Samoan prop Kylie Leuluai for Sunday's Super League game at Warrington after he became the latest victim of a tackling technique that the Rhinos coach Brian McClennan describes as a growing concern. Leuluai suffered ankle damage that could rule him out for several weeks as a result of the impact of a third defender going low during the champions' surprise home defeat by the Crusaders last Sunday. "My understanding is that more and more players are getting injured by this tackle, down under as well," said McClennan, who claimed that the Rhinos forwards Jamie Peacock and Carl Ablett have also been victims this season. "It's a difficult one," the former New Zealand national coach told the Yorkshire Evening Post. "It's not illegal, but it causes injuries. If the third man comes in from the side, you're all right. If he comes in from the back, and you don't see him, your body goes forward, but your foot gets locked in the ground, it gets hyperextended and that causes injuries. We have had three of those this year and it's frustrating. "I don't imagine anyone's purposefully gone out to do this, but it is frustrating when it happens to your players. We'll encourage players to tackle around the legs too, but you have to take a bit of care when you come right around the back." Leeds are also likely to be without their former New Zealand full-back Brent Webb for the trip to Warrington after he suffered an ankle injury in training. The game at Headingley also took its toll on the Crusaders, who were down to 14 players in training at the start of this week ahead of Sunday's home game against Wakefield Trinity. The Crusaders coach Brian Noble said that Gareth Thomas remains at least a fortnight away from recovery from a groin problem. The Welsh club, who retain a realistic chance of qualifying for the top eight play-offs in only their second Super League season, have confirmed that two of their remaining home games this season will be switched from Wrexham to Neath to show their ongoing commitment to the development work going on in South Wales. They will now play Castleford at the Gnoll, which is the home to the South Wales Scorpions who now play in the Championship, on 25 July, and the game against Harlequins that was postponed because of a waterlogged pitch over the Easter weekend will be played on 7 August. The second Hull derby of the season has also been rearranged and will now be played on a Thursday night, 15 July, at the KC Stadium to allow live coverage on Sky. Hull's gifted but fragile 22-year-old three-quarter Craig Hall is thought to be considering a move across the city to Hull KR, who are also close to agreeing a new one-year contract with their ball-playing Australian forward Ben Galea. Wakefield Trinity have confirmed the story broken on the Guardian website last night, that their coach John Kear is to stay with the club despite an approach from the Catalans Dragons. "John has been a key component of our club since he joined us during the 2006 season and is contracted until the end of next season," said Wakefield's chief executive James Elston."As a member of the club's board of directors, John is playing a major role in helping us secure a new Super League licence, and establishing a recruitment programme for 2011, together with a flourishing youth development operation." Kear said: "I was flattered to be identified by Catalans Dragons and interested to hear of their plans for the future. However, more than four years of my life have been invested in the Wildcats' progression. We are achieving Super League recognition with our regular top-eight status, including a best-ever top-five spot last season, and our extensive development of young players. We have already launched our recruitment programme for the 2011 season and are looking forward to providing a solid rugby base for the club's licence application to complement the progress being made with the plans for a new stadium."
