Rugby: Saturday's Premiership groups: Francois Hougaard begins for Worcester.

All the group news for Saturday's Aviva Premiership conflicts, including Bath v Wasps at the Recreation Ground. 

Scotland focus Duncan Taylor comes back to the Saracens beginning line-up, with the Six Nations taking a one-week break. He comes into the side at outside focus where he accomplices captain Brad Barritt in the midfield. Barritt drives the side without Alistair Hargreaves, who is precluded of the diversion with a lower leg damage. 

Somewhere else in the backline Ben Ransom turns with Marcelo Bosch at full-back, while Richard Wigglesworth comes into the side at scrumhalf with Ben Spencer returning to the seat. 

USA global Hayden Smith replaces Hargreaves, and begins nearby Jim Hamilton in the second line. 

Then Gloucester have rolled out five improvements to the side that beat Harlequins a week ago. 

Three of the progressions are in the pack, where Nick Wood, Jeremy Thrush and Ross Moriarty come in for Paddy McAllister, Tom Savage and Ben Morgan separately. 

Behind the scrum, Callum Braley gets approval over Willi Heinz at scrum-half and Mark Atkinson joins commander Billy Twelvetrees in the midfield set up of Bill Meakes.
