According to the promoters, six-time world champion Julio Cesar Chavez will be at ringside Friday at the National Guard Armory in Northeast Philly to watch the rematch between Angel Ocasio and Jason Sosa. The two area lightweights fought to a majority draw in their first encounter.

Chavez will be joined by his son, Julio Cesar Chavez Jr., in a marketing effort for an energy drink, the promoters said.
