Rocky's health plot hole
In Rocky V it was made very clear that Rocky had suffered severe brain trauma. It was evident in the brain scans that the doctors took of him at the beginning of the movie. They also said that the damage is permanent, it would never heal.
Yet in this movie, Rocky is given a clean bill of health by the medical team. Was the medical team THAT incompetent???!?!?!
In fact Rocky's health has been a plot hole in most of the movies. After Rocky's first fight with Apollo, his right eye is severely damaged. The doctors forbid him from fighting unless he wants to go blind. Yet he fights Apollo in Rocky 2, Clubber Lang (twice) and 10 other contenders in Rocky 3, Ivan Drago in Rocky 4, Tommy Gunn in Rocky 5, Mason Dixon in Rocky 6. And yet his eye is completely fine.
