Pg 233 of Everett Skeehan's book on Marciano: "it was discovered that Marciano's punches had BROKEN blood vessles and DAMAGED bones in his (LaStarza) arms."
Mr. Skeehan's book is wonderfully written and his hyperbole of the fights makes his piece a fantastic read. But much of the hyperbole is just that. The reason he didn't cross the line and say Broken blood vessles AND BROKEN Bones in his arms is becuase it simply isn't true.
The word damaged can mean just about anything. Lastarza had bruises on his arms and broken Blood vessles. No broken arms.
When ever I read something that seems a bit much, such as the above, I try to get a secondary source validation. You won't on this account, becuase A-Skeehan never made the statment about broken bones and B-It never happened.
