I remember reading about this when it happened. Platz waz trying to outdo his 81 shape which was phenomenal. He was training like a man possessed. be was known for his intensity and was in incredible shape a few weeks before the show tore his biceps. didn't want to waste all the effort he put into prepping for that show and decided to go through with it. only later admitting he should have gotten it fixed immediately and skipped the show. later on like 85, 86, the bicep had healed quite nicely but his career was ready on the downside by then.
