LEEDS will put cup glory and league relegation worries to one side tonight when they take on Worcester for a European final place.

The Tykes must not only overturn a nine-point first leg deficit but beat Worcester with only one survivor from their cup final starting XV -- wing Tom Biggs.

"We face a hectic programme over the next week, so it is important that we use our squad accordingly," said Leeds rugby director Phil Davies, whose team's Premiership fate will be decided by two games in five days against Harlequins and Bath.

Among the wholesale changes, England Under 19 World Cup squad member David Doherty replaces injured full-back Iain Balshaw, David Rees and Tim Stimpson forge the centre combination and flanker Dan Hyde takes over as captain.

"If the first leg is anything to go by, the spectators are in for a real treat," Davies added.

"We have had some real tussles with Worcester down the years, but especially so this season. Worcester gave us a tough examination at Headingley earlier this term, and they have beaten us twice at Sixways since then."

The Warriors, who won the first leg 43-34, also hand an opportunity to fringe first-team players, with centre Duncan Roke, prop Dylan Hartley and flanker Neil Mason featuring in a team led by full-back Daren O'Leary.

At stake is a place in next month's Shield final -- to be played at the Kassam Stadium in Oxford -- against French opponents Auch or Bayonne.
