PGA Tour player Marc Leishman said that his caddie, Matt Kelly, wasn't to blame for the bagman brawl Thursday between Kelly and James Nitties's caddie, Grant Buchanan, at the Australian Open, according to Michael Chammas of the Sydney Morning Herald.
"I don't think me or Matty have got anything to worry about," Leishman said.
"I was there and he (Kelly) didn't do anything.
"He stood there, copped what he got and didn't do anything apart from that. I was proud of him, to be honest."
The two caddies came to blows near a chipping area of the Lakes course in Sydney just before the start of the first round of the tournament, according to the report.
Fairfax Media saw punches being thrown before the pair fell to the ground and continued wrestling in front of players and spectators.
The men were eventually separated, but not before Kelly sustained a cut above his lip and was forced to leave the course to wash the blood from his face.
According to Chammas, the incident stemmed from an altercation between the pair at the Star casino earlier in the week.
"Matt was a good friend of mine, [or] so I thought,'' Buchanan said. ''He said some things that offended me and I approached him to clarify it and clear the air, and he pretty much laughed in my face."
PGA Tour of Australasia officials are investigating the incident, and that the caddies could face disciplinary action, according to the Associated Press.
Tournament director Andrew Langford-Jones said decision on any disciplinary action would be determined within a week.
"Our members in no way condone this behavior, and we are saddened the incident has drawn attention away from this great tournament," he said.
