I'm a predator fan first and foremost, but just playing devil's advocate here, it doesn't seem at all ridiculous that the predator knocks the alien down? Going by the original movies, there's nothing to prove that a predator should be able to manhandle a bug like that. The alien should be at least on par with the predator in meele, but as the situation stands now, the predator is head and shoulders above the rest. Just doesn't seem right to me.
