From the U.S. Open: no disciplinary action taken against caddie

I just talked to a USGA official, who said there would be no disciplinary action taken against Tony Navarro, the caddie for Adam Scott. Navarro went under the ropes and, according to a report in the San Diego Union-Tribune, was involved in an incident with fans. The two fans, a father and son, Thomas W. Campbell and Thomas J. Campbell, were rowdy and unruly and said something to Scott's caddie. Then, Scott went unter the ropes and a scuffle ensued.
