There is no new injury updates from their 2-1 defeat at Middlesbrough last Friday.
Mason is "disappointed" by the past two results after two losses has left them outside the top six but says the side "worked well this week" and are hoping to stop the rot against the Foxes.
On Leicester's Harry Winks, who Mason worked with while at former club Tottenham Hotspur: "When you're academy player and someone has walked the steps you want to take, it's something you aspire to. I have a really good relationship with Harry, I have had a good relationship with Skippy [Oliver Skipp, also a former Spurs player] too.
"They've both had really good careers to play for Tottenham, it's not an easy thing to do. Now they are at Leicester and I'm sure they are determined to put in a performance and hopefully our players will put in a performance to overshadow that."
Mason confirmed that strikers Josh Maja and Aune Heggbo could potentially both start "at some point" having largely favoured only one striker this term.
He said: "They've got different attributes, currently they are only fit strikers so that comes into the thinking as well. Josh has a massive part to play in this team for the whole of this season and we are looking forward to it when he does."
