The left-back missed the Super Eagles’ semi-final victory over South Africa with a hamstring injury but is potentially in contention to feature on Sunday.
Nigeria coach Jose Peseiro told reporters: “He was partially involved in Friday training and we will check his condition again tonight before we make a decision.”
Having switched to a 3-4-3 formation midway through the group stage, Nigeria have only conceded two goals all tournament.
Sanusi had been an ever-present until the semi-final, when he was replaced by Bright Osayi-Samuel as Ola Aina switched to the left flank.
Osimhen has only scored once in Ivory Coast, in their opening group game.
Peseiro said: "He doesn’t play like he is the star. He fights for the team and is completely unselfish.
"He knows he is an important player and he gives us the best energy. He has suffered a lot in this tournament with all the attention he receives from the opposing defenders because he knows it is a team game."
