 Paul heads a cast of England internationals |
James Simpson-Daniel and Henry Paul will meet fellow England caps Dave Walder and Jamie Noon in the first round of Saturday's Middlesex Sevens. Gloucester's date with Newcastle is the pick of the early ties at Twickenham's traditional season curtain-raiser.
Fellow England internationals Olly Barkley and Ollie Smith will also feature as Bath and Leicester meet in one of five all-Premiership clashes.
Northampton, the defending champions, start against London Welsh.
The Saints were the first Premiership club to win the tournament since 1999 when they beat Newcastle in the final a year ago.
London Irish and Harlequins will meet in a rehearsal for their opening Zurich Premiership match on 4 September.
The Exiles feature England Sevens players Paul Sackey and Geoff Appleford, while Quins include exciting wing Ugo Monye.
Other England Sevens players on display include Pat Sanderson and Ben Gollings (both Worcester), Peter Richards (Wasps), Kris Chesney (Saracens), Leon Lloyd (Leicester) and Simon Amor (Gloucester).
