Ryan Mills and Cooper Vuna return to boost Worcester Warriors for Northampton Saints match

With Jackson Willison getting married and Ben Te'o on England duty, head coach Carl Hogg has called upon Mills who will make his first appearance of the season.

Vuna also returns for the first time since featuring in Warriors' 11-9 win over Newcastle Falcons, while fit-again Bryce Heem has been named on the bench.

Mills and Vuna are two of five changes to the Warriors team who lost 36-14 at Harlequins in their last Premiership outing.

Flanker Dewald Potgieter makes his first Premiership start of the campaign and Niall Annett and Wynand Olivier have also been restored to the starting line-up.

Nineteen-year-old Jamie Shillcock starts at fly-half with Jonny Arr joining him in the half-back combination while Dean Hammond also keeps his place on the wing.

Heem could make his long-awaited return from injury having yet to feature this term.

There could also be top-flight debuts from the bench for academy youngsters Jack Singleton and Andrew Kitchener along with scrum-half Michael Dowsett, who arrived at the club earlier this month.
