It's worth mentioning that Frank has been weighing the decision heavily, and 2-3 particular team leaders were also consulted a long time ago. Frank considering booting Dom doesn't have anything to do with his game. A four letter word and an injury were mentioned. It has to do (this part is speculation) with Frank wanting to make sure he doesn't sacrifice his coaching mantra and set any bad examples.
So, take that fwiw until we hear about the if/when.
