DAREN O'Leary will say goodbye to Worcester wearing the captain's armband.

The winger, who has enjoy-ed two fine seasons with the Warriors, will sign off his Sixways career in tomorrow's European Shield final (5pm).

Former Gloucester and Harlequins man O'Leary -- who will go down as one of the most prolific Premiership predators -- will not be offered a new Worcester deal for next season's campaign.

Worcester face Auch at Oxford's Kassam Stadium and, despite a host of injuries and player unavailability issues, name a strong squad for the season finale.

Thomas Lombard will play at outside-centre alongside Gary Trueman, while Matt Powell features at scrum-half.

The Sixways side have endured a number of problems making sure the game goes ahead because of front row injuries, but Tony Windo, Ben Daly and Steve Sparks are named in the side with Dylan Hartley and Chris Hall pencilled in on the bench.

The Warriors had wanted to re-register Neil Lyman for the final but, because of strict regulations, have been forced into naming Sparks, who has been carrying various injuries, at tight-head.

It means that uncontested scrums are a likely occurrence at some point in the match and head coach Andy Keast believes that the ERC regulations over player registration need to be more flexible in the future.

"Steve Sparks has had a couple of weeks rest so that is good," said Keast. "But the test will be when he hits the first scrum.

"I hope the game doesn't go to uncontested scrums but it wouldn't surprise me. ERC need to look at the whole registration situation. We've sent them forms, documentation about our players and asked for common sense to prevail. Unfortunately, this time it hasn't.

"There is a trophy to play for so that is motivation, but there are also players whose futures are uncertain. It's a relevant game for Siaosi Vaili, Neil Mason, Paul Sampson and Jon Hylton."

Pat Sanderson is not involved after Worcester decided not to risk him only days before he jets off to Canada to skipper England for the Churchill Cup campaign.

"Pat is fit to play," added Keast. "However, he's committed himself to Worcester wholeheartedly all season and now it's pay-back time. We want to keep him fresh to captain his country. If he played against Auch and got injured, we would never forgive ourselves."
