The manager told the team's website: "Zak has been in non-contact training all week so will be available for selection and Matty James came off the other night as a precaution so we'll keep an eye on him, but all in all we're injury free.
"Ben Marshall is okay now too, so he'll also be available, so it's quite nice to go into a game with a full squad to select from.
"This season feels as though it has been going for a number of weeks already, and it's a chance for our supporters to see us at home for the first time. It's a big fixture against Leeds and straight away we'll be looking to see whether we can keep our good form going."
Leicester beat Middlesbrough in their opening game of the season last week.
