Bromby sits out a one-game ban under the totting-up procedure and Leicester winger Gradel is cup-tied but otherwise manager Simon Grayson has a full-strength squad to choose from.
Grayson is likely to recall Jason Crowe to fill in for Bromby, while Bradley Johnson and Jonny Howson are battling for returns to the starting line-up.
Jermaine Beckford has scored four goals in his last two matches to take his tally to 19 for the season and he is expected to partner Luciano Becchio up front.
Leeds moved eight points clear at the top of League One after Monday's win at Stockport and Grayson said: "We were back in on Wednesday and while there are a few tired bodies, there are a no new injuries.
"The lads had Thursday off and then we'll start counting down on Friday, working towards the game."
Kick-off is at 1pm.
