Ryan Mills and Cooper Vuna return to the starting line-up for Worcester's Premiership clash with Northampton at Sixways on Friday.
Centre Mills is set for his first appearance of the season while winger Vuna returns for the first time since featuring in Warriors' win over Newcastle Falcons at the start of October.
The pair are two of five changes to the Warriors team which battled Harlequins in their last Premiership outing, with flanker Dewald Potgieter making his first Premiership start of the season and Niall Annett and Wynand Olivier restored to the starting line-up.
19-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.
Warriors' 2015/16 Player of the Season Bryce Heem is named on the bench and could make his long-awaited return from injury having yet to feature during this campaign.
There could also be Premiership debuts for Academy youngsters Jack Singleton and Andrew Kitchener along with scrum-half Michael Dowsett, who arrived at the Club earlier this month.
Meanwhile, Ben Foden will become the 55th player to reach 200 Northampton Saints first-team appearances when he runs out at Sixways in Friday's Premiership clash.
The full-back returns to the starting line-up after coming off the bench in last Saturday’s Anglo-Welsh Cup win over Gloucester as one of nine changes to the team.
