Kris Welham has been dropped from Hull KR's 19-man squad for the visit of Warrington Wolves on Friday.
The centre has struggled to find his best form this season and looks to be paying the price for Rovers' poor showing on the left-hand side of defence, which was heavily exploited by Castleford in a 54-12 defeat last time out.
Sandercock has made four further changes. Kevin Larroyer, Jordan Cox, Ben Cockayne and Rhys Lovegrove all picked up injuries in the defeat at Castleford and drop out.
Greg Eden comes in for Cockayne at full-back, while Liam Salter, Keal Carlile and Jason Netherton all return.
Aaron Ollett makes his first appearance in the 19-man squad this season.
Mick Weyman keeps his place after seeing his two-match ban for abusive language overturned on Tuesday night.
For Warrington, Michael Monaghan and Richie Myler have both been left out of Tony Smith's squad after picking up injuries in the 46-10 cup win at Bradford on Sunday.Hull KR squad: Burns, Carlile, Costigan, Eden, Gardner, Green, Hall, D.Hodgdon, J.Hodgson, Horne, Keating, Langley, Netherton, Ollett, Salter, Ulugia, A.Walker, J.Walker, Weyman.
