Sounds like managing this will be an ongoing challenge. He had the same situation in college. The man possesses a tremendously strong body from the shins up, but , apparently, weak ankles. Sort of like a 50 story skyscraper built on top of wooden poles. If there was a simple solution I’m certain that it would have been tried. I remember in college, every player had to have their ankles taped before the game, and I don’t recall that many ankle injuries. However, back when I played, running backs didn’t have the size or speed that today’s backs possess. 
I guess it’s going to be a game to game situation for the rest of his career. More reason to have quality backup talent.
