Injuries and a refusal could hit Cup run.

Steve Holland faces a potential injury crisis ahead of the trip to Boundary Park this Saturday. Julien Baudet is the biggest doubt with a back injury while Danny Woodards and Billy Jones have slight problems but should be fit.
Add to the fact that Man Utd have refused the Railwaymen to play David Gray this Saturday in the second round tie and Holland may have to jig his defence about.
If Woodards is passed fit he will be expected to partner Chris McCready in the heart of the defence while on loan player Elliott Bennett looks set to play right back.
Former striker now defender Mat Bailey looks set for the bench and could be called upon as back up for the defence is required.
Nicky Maynard looks set for a place on the bench and could feature at some point after coming through a in house practice game this week.
