Not smart to pick a fight with a former world champion.
Minding his own business, Rocky Lockridge, who in his prime beat Roger Mayweather, uncle of Floyd, to win the WBA super-featherweight title, is approached by a man shouting abuse.
He faces up to the former boxer while onlookers attempt to persuade Lockridge not to take action. But he ignores them and delivers a left-right combination which leaves his aggressor out cold.
