Canterbury foward Frank Pritchard will miss Saturday's round two match up with St George through suspension.
Pritchard was found guilty of a grade one careless high tackle at the NRL judiciary and given a one match ban following his high shot on Penrith's David Simmonds.
Simmonds had to be helped from the field and was later hospitalised after being collected in the head by Pritchard's shoulder.
Coach Des Hasler has yet to name Pritchard's replacement.
Tony Smith has insisted that his Warrington side will not allow thoughts of possible Challenge Cup glory to disrupt their focus.
With the glass ceiling to Super League being removed from next season, the path to the top flight opens up for Cumbria once again.
The Super League play-offs in their current form may attract some criticism, but they are keeping the season alive for several clubs in the bottom half.
