SOUTH Africa international Wynand Olivier will make his Worcester Warriors debut when Wasps visit Sixways tomorrow (3pm).

The centre signed for the club earlier this week and goes straight into the side as a new Midlands rivalry begins on the pitch.

Olivier lines-up alongside Alex Grove, while Chris Pennell, Sam Smith and Tom Biggs make-up the back three.

The half-back combination sees Ryan Lamb partner Charlie Mulchrone.

Warriors director of rugby Dean Ryan has included 12 replacements on the bench as he looks to give the players in his squad further match action.

Warriors: Pennell; Smith, Grove, Olivier, Biggs; Lamb, Mulchrone; Ruskin, Annett, Schonert, Barry, O'Shea, Mama, Lewis, van Velze. Replacements: George, Leleimalefaga, Rees, Sanderson, Cox, Arr, Heathcote, Fatiaki, Betty, Ryan Mills, Dowson, Howard.
