A SpriteRenderer is not displaying the sprite when set the second time - unity3d

Question

I have a cell prefab in which I have a GameObject with SpriteRenderer. I am instantiating multiple instances of a prefab and feeding a sprite for every instance. The first cell instance is displaying the given sprite but the second one is not.
Here I am creating two instances of a Cell and feeding the Cell with a sprite from mIconManager:
private void PopulateCells()
{
for (var i = 0; i < 2; i++)
{
GameObject goPrefab = Instantiate(goRawPrefab, CalculateCellPosition(i), Quaternion.identity, trBoard);
CellController cellController = goPrefab.GetComponent<CellController>();
cellController.FillContent(mIconManager.getSprite(i), i);
}
}
This is a snippet from CellController script attached to a Cell:
private void Awake()
{
mIcon = GameObject.Find("IconSprite").GetComponent<SpriteRenderer>();
mCardBg = GameObject.Find("CardBg").GetComponent<SpriteRenderer>();
}
public void FillContent(Sprite sprite, int index)
{
mSprite = sprite;
mIcon.sprite = mSprite;
}
This is my Cell prefab:
When I run the code, the second instance of a prefab is not getting the sprite.
I checked the first prefab's SpriteRenderer in the inspector while the game is running, and it said anchovies for the sprite - the one I gave via FillContent() method. Interestingly, the second prefab's SpriteRenderer component shows EMPTY sprite.
First Prefab's SpriteRenderer while game is running:
Second Prefab's SpriteRenderer while game is running:
Am I missing something? I searched through the internet and found some posts saying "SpriteRenderer is not loading sprites the second time" but they were not answered and the ones that were answered didn't solve my problem.
P.S. I also tried setting the SAME sprite for both instances of the Cell prefab - still no success.
P.S.2. I logged the sprites that are given to the both instances of the Cell prefab and they were not null or empty. I even did Debug.Log(mIcon.sprite) which both instances logged the name of sprites I provided.
Edit:
Logging when giving the same sprite to both instances:
public void FillContent(Sprite sprite, int index)
{
Debug.Log("hop, spriteName : " + sprite + ", prefabIndex : " + index);
mSprite = sprite;
mIcon.sprite = sprite;
}

Try Filling It with the same sprite twice the code seems fairly normal
This will Help me debug it al lil more ie.
private void PopulateCells()
{
for (var i = 0; i < 2; i++)
{
GameObject goPrefab = Instantiate(goRawPrefab, CalculateCellPosition(i), Quaternion.identity, trBoard);
CellController cellController = goPrefab.GetComponent<CellController>();
cellController.FillContent(mIconManager.getSprite(1), i);
}
}

Okay, it turns out the problem was not related to the SpriteRenderer. SpriteRenderer was working as expected. However, the way I got a reference to the SpriteRenderer was not correct.
In CellController, I was getting a reference to the SpriteRenderer with GameObject.Find..., the thing is it was not giving me a reference to a instantiated prefab clone, but to the first prefab clone.
private void Awake()
{
mIcon = GameObject.Find("IconSprite").GetComponent<SpriteRenderer>();
mCardBg = GameObject.Find("CardBg").GetComponent<SpriteRenderer>();
}
Instead, I used tranform.Find and everything worked as expected.
