Andy Ruiz Jr greets Anthony Joshua's mother with friendly handshake ahead of Saudi Arabia rematch

Andy Ruiz Jr may have four world title belts, but he's still playing the role of humble challenger ahead of his heavyweight rematch with Anthony Joshua. 

He lured Joshua into a false sense of security in New York back in June and the California-born fighter has been equally understated in Riyadh this week.
