The Australian pair have been carrying knocks in recent games, and coach Craig Sandercock has decided that two games in four days is too much for them.
Both sides won their respective derby matches on Friday, with Wigan’s win lifting them to first place in Super League.
The Warriors have won the last nine matches between the two sides.
Hull KR 19-man squad: Salter, Brown, Walker, Horne, Griffin, Latus, Mika, Tuimavave, Welham, Beharrell, Hall, Paea, Carlile, Cox, Caro, Beaumont, Eden, Lovegrove, J Hodgson.
Wigan 19-man squad: Burke, Charnley, Crosby, Lloyd, Farrell, Flower, Goulding, Green, Hughes, McIlorum, O’Loughlin, Richards, Spencer, Smith, Taylor, Thornley, L Tomkins, S Tomkins, Tuson.
Prediction: The new leaders should make light work of a Rovers side without star man Dobson and others – away win.
Wigan have won their last nine meetings with Hull KR. The Robins’ last win was 20-12 at the JJB Stadium (as it was then known) on 15 May, 2009.
