Warriors welcome back Wales winger Josh Adams and captain GJ van Velze for their Gallagher Premiership derby match with Gloucester Rugby at Kingsholm on Saturday (kick-off 3.00pm).
Adams returns to club duty after impressing for Wales in their recent Autumn Internationals against Australia and South Africa.
Number eight Van Velze missed last Friday’s victory over Harlequins at Sixways due to injury but he has regained fitness and will take his place in the middle of the back row at Kingsholm.
Warriors have been forced to make two more changes to their starting XV with scrum-half Francois Hougaard and openside flanker Sam Lewis both ruled out by injuries.
Michael Heaney, a summer signing from Doncaster Knights, will make his first Premiership start in Hougaard’s absence with Matti Williams, who started at Bath two weeks ago, returning to the back row in place of Lewis.
Tighthead prop Gareth Milasinovich will reach the landmark of 50 career appearances for Warriors if he comes off the bench.
Milasinovich, 25, joined Warriors from the University of Johannesburg three years ago and made his senior debut in the 2015/16 season.
