According to the US Marshall who escorted Gotti during his court trial, john gotti sr was put into solitary confinement for a fight at MCC

Anyone know who he fought with? No idea if it's true because Gotti was worshipped seeing it was in NY plus he had sammy frankie around and various guys so doesn't make sense Gotti would personally get into a fist fight

The one where he was beat down in Marion, fair enough. He had zero guys around and was all alone etc
