Steve Morison remained coy on whether Kieffer Moore is back fit for Wednesday's game.
The striker was rested for the Preston clash last weekend and it was hoped he would be back available for Hull City on Wednesday night. While Morison didn't rule it out entirely, the forward was pictured in the club's training pictures on Tuesday, he did little to instil confidence.
Joe Ralls is also touch and go after his illness at the weekend. Tom Sang played for the under-23s against QPR on Tuesday and Morison ruled out his involvement on Wednesday night, too.
Isaac Vassell and Sam Bowen remain absent.
