Hibs savoured a 1-0 victory over Hearts last Sunday as the holders crashed out of the William Hill Scottish Cup at the first hurdle in a result which exacted some revenge for the Edinburgh derby defeat at Hampden in May.
After the joyous celebrations at Easter Road, Fenlon's side return to SPL duty two points above Inverness in second place in the SPL and one point behind leaders Celtic.
Fenlon said: "When we lose games we're disappointed but they get over it fairly quickly and when we win them the same thing - the key is to put it aside.
"Beating Hearts means a lot more to the supporters, but from our point of view it's just another win and we need to move on from it.
"With the game coming thick and fast again on Saturday, that's where the focus has been."
Top-scorer Leigh Griffiths is a doubt with an ankle injury, while midfielder Gary Deegan (jaw), captain James McPake (back) and his fellow defender Tim Clancy (groin) remain out, but should return soon following lay-offs.
Inverness have performed well of late and Fenlon recognises the task his side face.
The Irishman said: "Their form has been fantastic. Away to Aberdeen, away to Celtic and picked up six points. That in itself is a fantastic achievement.
"We're confident ourselves at the moment, so hopefully it will be a good game."
