WORCESTER Warriors have made two changes to their starting line-up for tomorrow's Aviva Premiership clash with Exeter Chiefs at Sixways (3pm).

Back row Dewald Potgieter returns to the squad following an ankle knock, while Jaba Bregvadze replaces the injured Jack Singleton at hooker.

Elsewhere in the pack, Ryan Bower is rewarded with another Premiership start after impressing in last weekend’s win over Saracens, while Donncha O’Callaghan leads the side once again.

The backline remains unchanged.

In the replacements, Joe Taufete’e could be set for his first Premiership appearance, after returning from the USA for the birth of his first child.

Val Rapava Ruskin is on the bench after recovering from a back problem, while Sam Lewis is dropped to the bench.

Rob Baxter says his Exeter Chiefs squad are ‘fully focused’ on the task ahead.

Fresh from a hard fought draw against table-toppers Wasps last Sunday, the Chiefs will be looking to consolidate their top three position by inflicting yet another league defeat on their hosts.

In nine previous top flight meetings between Worcester and Exeter, it’s been a whitewash of victories for Devon’s finest.

Another this weekend would not only take that record into double figures but, more importantly, ensure Baxter’s side keep up their pursuit of Wasps and Saracens at the summit of the table.

However, the Chiefs head coach knows all too well that the Warriors - particularly on home turf - will be no pushovers.

“It’s a big game for us and if we want to achieve anything at the end of the season, it’s what we do now that ultimately matters,” said Baxter.

“We’ve had a good training week, we’ve got guys back up to speed into the Premiership after a month of action in Europe and the Anglo-Welsh, and we look in good shape.

“What we’ve talked about this week, however, is the importance of everyone being sharp and fully focused and that when we hit the pitch we do everything flat out.

"That is what we are good and it’s what tends to suit us. We have to make the game very attritional over the 80 minutes for every opposition that we play.

“There were times last week [against Wasps] when we perhaps over managed the game and that’s not great for us. We just need to focus on ourselves, get things right from the outset and really look to take the game to Worcester.”

He added: "They looked well organised and very comfortable with what they are doing,

“They had good energy, worked hard for one another, so it’s should be a fantastic challenge for us.

“What I like about the weekend is that both sides are fighting for something. Worcester are fighting to prove they can climb clear of the relegation zone and push forward as a club, while we are fighting to consolidate a place in the top four and be on course to be part of those big games at the end of the season."
