Rea shuffles his pack as play-off chase continues

The Broncos are the team in possession of sixth place, but they have a tough task at St Helens today. They have the recently re-signed Zeb Luisi back after illness and Rob Purdham returning from a shoulder injury at Knowsley Road.

Dave Highton is out with a dead leg, which means that London's coach, Tony Rea, is likely to persist with the experiment of playing Lee Hopkins at hooker. Despite defeat at Leeds, that switch was a success last week.

As well as Luisi, London have also agreed a new, one-year contract with their former Junior Kiwi forward, Filimone Lolohea.

Saints have the prop forward Mark Edmondson in their side after he recovered from a cold and he is keen to sign off with a strong end to the season before joining the Sydney Roosters next year.

If London are beaten, either or both of their rivals could draw level with them on points after tomorrow's games.

Huddersfield, with impressive wins over Wakefield and Warrington over the last two weekends, will be confident against the already relegated Leigh tomorrow.

They have an extra boost with the return ahead of schedule of the Australia Test centre Michael de Vere after a broken hand. They will be without Jim Gannon for the rest of the season, however, so Chris Nero will switch to the pack at the Galpharm Stadium.

Leigh give a debut to St Helens' reserve scrum-half, Carl Forber, who has joined them on loan for what remains of their season in Super League.

Wigan have David Vaealiki and Danny Orr back after injury for their trip to the cup finalists Hull, who will rest Paul Cooke and Richard Horne with next Saturday's big match in mind.

Warrington, whose form has gone into a nose-dive since they announced that Andrew Johns was joining them next month, should get back to winning ways at the almost-doomed Widnes.

The Wolves have Lee Briers and Graham Appo back from injury as they try to push back up the table from the fifth place into which they have slipped.

Widnes have gained Andrew Emelio but have lost Jon Whittle to a season-ending quadricep injury as they try to cling on to their Super League spot.

In the battle for promotion from National League One, leaders Whitehaven go to third-placed Hull KR for a real crunch match.

Most people's pre-season favourites for promotion, Castleford, are currently second and cannot afford a slip-up against fourth-placed Halifax.
