Steve Cotterill will look to use his resources carefully for vital league games against Southampton and West Ham, separated by a televised trip to the King Power Stadium to face the Foxes.
"I need to see how this weekend's game goes, against Southampton, before we even think about Leicester, before I select a team for that game," he told the Evening Post as he awaits the return of Ishmael Miller, Brendan Moloney and Wes Morgan from injury.
"Two days after the cup game, we travel down to London for the game against West Ham.
"So I have to look at the week, as a whole, quite carefully, when it comes to the three games.
"At this moment, it is our next game that always has to take priority, nothing more."
