One of my nonsponsor books has a line with large max wager on wether or not they will get in a skirmish at the press conference or wiegh in. Skirmish defined as physical contact. Seems like there is much higher likelihood of it not happening than happening without knowing much. What is the history between the two guys? Do they hate each other and how common is it to have a skirmish in prefight events? Any thoughts greatly apperciated.
