NEW signing Tevita Cavubati makes his full debut as Worcester Warriors travel to Kingsholm to face Gloucester in the Aviva Premiership tomorrow (2pm).

The Fijian lock will start alongside Donncha O'Callaghan with Darren Barry dropping to the bench as director of rugby Dean Ryan names the same 23 who lost 27-13 at Sale Sharks last week.

Internationals Chris Pennell and Cooper Vuna join Tom Biggs once again in the back three, while Springbok Wynand Olivier partners Ryan Mills in midfield.

Tom Heathcote and Jonny Arr look to cement their half-back partnership to complete a strong Warriors back-line.

Captain GJ van Velze lines up alongside the Premiership's top-tackler Phil Dowson and Marco Mama in the back row, while Na'ama Leleimalefaga, Niall Annett and Nick Schonert complete the front row.

Wales international flanker Ross Moriarty will line up on the blindside flank as Gloucester make just one change.

Moriarty returns after Rugby World Cup duty with Wales and takes over from Lewis Ludlow.

The only other new face in the match-day 23 sees on-loan hooker from Bristol, former Worcester player Chris Brooker, named among the replacements.

The teams are separated by just one point in the table after two rounds of action with both having won one game out of two to date.

Warriors: Pennell; Biggs, Olivier, Mills, Vuna; Heathcote, Arr; Leleimalefaga, Annett, Schonert, O'Callaghan, Cavubati, Dowson, Mama, van Velze. Replacements: George, Rapava Ruskin, Rees, Barry, Cox, Mulchrone, Lamb, Howard.

Gloucester: Sharples; Halaifonua, Twelvetrees, Meakes, May; Hook, Heinz; McAllister, Hibbard, Afoa, Savage, Kalamafoni, Moriarty, Kvesic, Morgan. Replacements: Brooker, Thomas, Doran-Jones, Stooke, Rowan, Braley, Burns, Purdy.
