Not an identical situation but Blake Griffin missed his first year due to injury. Came back the next year, had a great year, and won ROY over John Wall. In fact, Griffin was a unanimous winner so nobody officially protested his extra year in the NBA.
Forgot about him. I remember Julius Randle broke his leg in the first few minutes of his first NBA game and wasn't eligible for RoY his second season because he had technically played in a regular season game.
