I was watching this card(Miami, Florida)
http://www.boxrec.com/show_display.php?show_id=49008
and the third bout was
Giorbis Barthelemy vs. Jesus Arroyo 8 rounds Light middleweights. Somehow this bout found it's way on different card.
The database has this bout listed on the same night but in this card(Boca Raton, Florida)
http://www.boxrec.com/show_display.php?show_id=21215
The result was a third round stoppage at 2:15
The referee for the Barthelemy-Arroyo bout was William Connors. Williams Connors was also the referee for the main event(Cuauhtemoc Gomez vs. Alimi Goitia) for the first card(in Miami). I doubt Connors got in his car after refereeing the main event in Miami and drove to Boca Raton to referee an undercard bout. But if needed as always video proof can be provided.
