We are missing three wingers due to injury and "personal reasons."
I doubt we'll get anyone on loan. Dave Scott played for Doncaster on the wing (and occasionally for us), has pace and can defend. So I think he's the best option for us under the current situation.
This leaves a vacancy at full back, which I suggest could be filled by Little Farrell. He'd still be able to link into the attack and weave his magic when the opportunity arises.
If, however, Dogfather is correct and both Brambani and Walker are unavailable, then I agree with you - Little Farrell should remain in the halves. I'd still have Scott on the wing - not sure who would play fb.
