WASPS wing recruit Paul Sackey has been given the seal of approval by former England skipper Law-rence Dallaglio as this season's Premiership title race hots up.

Sackey, signed from London Irish earlier this year, showcased his renowned finishing ability with two tries during the emphatic victory over Saracens last weekend.

And second-placed Wasps will want him firing on all cylinders again tomorrow when relegation-battling Worcester visit the Causeway Stadium.

A bonus-point victory could take the reigning champions above long-time league leaders Leicester if the Tigers lose at Saracens, meaning this season's automatic Premiership grand final place would be contested when Wasps visit Leicester on April 30.

"Paul was at Wasps as a youngster, and we really should not have let him go in the first place," said Dallaglio.

Fly-half Alex King misses out, hwoever, with a foot injury, so Mark Van Gisbergen moves from full-back to replace him and Voyce wears the number 15 jersey, with Sackey and youngster Thom Evans on the wings.

Tom Rees, meanwhile, continues in the back-row alongside Dallaglio and Joe Worsley, and he can expect an extended run after Irish international flanker Jonny O'Connor broke his hand during a club training session this week.

Worcester make one change from the side which defeated Newcastle last time out, with Daren O'Leary replacing injured wing Giscard Pieters.
