Lawler is injured and Salter's only had one short spell vs London, so I guess the one that jumps out is Addy.
The back row have all been a bit quiet but he's not stood out in a negative way. Maybe he's got a knock?
If Donaldson is at LF, then I assume Milton is in pole position for a bench spot. I did wonder if Abdull might go to LF, Quinlan to SO and Moss to FB, making room for Cockayne or Hodgson on the wing. Probably unnecessarily disruptive though, for all that we've been hit and miss so far.
Edit - Addy has a hamstring injury. I should have looked at the Rovers site.
