There´s any need to set to null a reference in this case?

private function initGame():void{  
game= new Game()  
}  
private function endGame():void{  
removeChild(game)  
//here, should I set game to null?  
}

then, to start a new game:

initGame()

In this case, do I need to set game to null at endGame? Or by adding a new game instance to game variable, the previous instance has no more reference and so is eligible for garbage collection?
