Ben Stevenson could be in contention to return from short injury lay-off, while City are short on defensive options...
Sky Blues midfielder Ben Stevenson has been in full training today after suffering a niggle, while Nathan Clarke, Farrend Rawson and Kevin Foley are all cup-tied.
Skipper Jordan Willis misses out through suspension, but Jordan Turnbull and Cian Harries will be available.
Russell Slade said: “Ben Stevenson had his first training outing today, he was injured before Saturday. The main thing is there will be changes, because people are unavailable for the fixture.
“That is a problem. There will be changes tomorrow night, but we’ve made those before and been successful. Let's hope we can do that one more time.
“Defence is a problem area, it is a headache. When someone is out you have to see it as an opportunity for someone else. Let's hope they can deliver.”
