Is Brook a "quitter?"

[Batman]

I wonder if the latest eye injury was in anyway helped along because he has a titanium plate in his right eye socket?
Obviously im no doctor but mayne that itself puts a lot of pressure and stress on the other eye socket, then 11 rounds of having it caved in non stop on top.

Seems crazy he has had the exact same injury in 2 back to back fights.

This is the question I asked in the other thread, I can't think of any type of underlying problem that would cause you to have weak eye sockets (sounds stupid even writing it) but to suffer 2 fractures of the same nature in 2 successive fights just seems bizarre to me.
