WORCESTER Warriors' England international Chris Pennell is one of two changes to the starting line-up from their last Aviva Premiership clash as they prepare to battle Harlequins at Twickenham Stoop tomorrow (3pm).

Pennell made his comeback from injury last weekend in the European Challenge Cup defeat to Brive but is set to make his first league appearance of the season on the wing.

Ben Te’o is named at inside centre for Warriors following his call-up to the 33-man England squad and replaces Wynand Olivier.

Academy youngster Jamie Shillcock keeps his place at full-back after signing a first-team deal earlier this week and joins a back-line that also includes Jonny Arr, Ryan Lamb, Jackson Willison and Dean Hammond.

The pack remains unchanged from the loss at Leicester Tigers three weeks ago although Val Rapava Ruskin is set for his 50th appearance for the club when he steps out at the Stoop.

On the bench, flanker Dewald Potgieter returns from a lengthy injury lay-off and could make his first appearance since scoring in the win at Newcastle Falcons in March, while Niall Annett is named as replacement hooker.

Academy youngsters Charlie Hewitt and Josh Adams are also on the bench alongside Springbok World Cup winner Olivier, who scored the last time the sides met in March as Warriors came away with a 21-15 win.

Quins make five changes to the starting team who played Edinburgh in European competition last weekend.

Club captain Danny Care returns and is joined in the back-line by Tim Visser, who has recovered from a minor injury, and inside centre Winston Stanley.

Jamie Roberts has been rested, while Harry Sloan is out for the rest of the season with a knee injury.

In the forwards, Will Collier is named at tighthead as Kyle Sinckler picked up a knock to his arm.

Charlie Matthews starts in the second row and replaces Sam Twomey, who sustained a foot injury.

Among the replacements, Mark Lambert will look to make his 200th appearance for the club.

Quins director of rugby John Kingston said: “We are looking forward to returning to the Premiership and are hoping to sustain our excellent home record.

"Worcester have shown already this season they are a quality outfit and we will need to be at our best to keep that run going.

“I have decided to rest Jamie as he is now straight into international rugby next weekend, while the England players will not be starting their autumn matches until the week after.”
