Joe on Conor McGregor's Leg Break

I don't have reliable information about a guest named "Joe" who specifically appeared on the Joe Rogan Experience to discuss Conor McGregor's leg break. The episode reference you provided (JRE #1683 with Andrew Huberman) discusses general topics and doesn't match this description. Without accurate details about this guest's identity, credentials, or expertise, I can't write an authentic bio that meets your standards of being specific and knowledgeable. Could you provide additional details about who this person is or clarify which episode they appeared on?
