Could this happen?

Could this actually happen in reality?

if the big dino were sick or injured, any pack predators would probably give it a go. I'd say yes.

I think it would depend. 
There was an article recently about how raptors didn't always hunt in packs. 

But old, weak, and infirm large prey would be an opportunity for a meal.

If the prey was the easiest  meal in the pack hunters' territory, yes.

No need to guess we have evidence in the Utahraptor block.

"Utahraptors likely hunted in packs, using their young as what Kirkland called “cannon fodder” so the larger raptors could move in for the kill. Kirkland thinks the herd came across an herbivore stuck in mud or quicksand when they, too, got caught and died."
