The Fijian international forward has not played for almost a year but is on course for a return to action at Scotstoun.
Last Friday's match was frozen out just before kick-off but the forecast looks more promising for the weekend.
A knee injury has kept the former European player of the year's services all season.
"Right now he's coming back from a long-term injury so the best option for him is in the second row when there's not so much of a demand in the open spaces when he's not got games under his belt," said the Warriors coach in The Scotsman.
"He hasn't played for almost a year now, since last February, which is such a long time. With the knee injury he's had he has to get the right exposure in the right position.
"The key difference with Leone is his ability to off-load. That can break a game up. When you're playing against well-organised defences you need a game breaker, someone who in a one-on-one situation draws more defenders and can then get the ball away.
"He's a nightmare to play against when he's on form. You could try to wrap him up with two or three players but he gets his hands free and those off-loads stick. Other players try that and they can't off-load or they don't stick. Leone can break open a game. And all you need is one off-load and all of a sudden you've got a line break and then you need to convert."
Nakarawa came through a training session on Tuesday and, provided there is no reaction, he will be in the squad for Saturday.
"He trained again today in what we call a red session - a high-intensity session," Wilson said. "He seems to have got through that. Obviously he will wake up tomorrow morning, another day off, and hopefully there is no flare-up with his knee, and if that's the case we should get him to a place where he'll have some involvement this weekend.
"If there's any last-minute issues that might knock it on a week, which it has done before with Leone. But hopefully he'll be involved this week."
