Golf officials are investigating a fight between two caddies near the practice chipping area at The Lakes before the first round of the Australian Open.
PGA Tour of Australasia officials said Friday that Grant Buchanan and Matt Kelly had to be separated after coming to blows as their players prepared for the opening round. Buchanan is James Nitties' caddie, and Kelly works for Marc Leishman.
The caddies were interviewed by tour officials and could face disciplinary action.
Tournament director Andrew Langford-Jones said "we've spoken to those involved and we still need to speak to a few more people."
Leishman had a 2-under 70 on Thursday, leaving him four strokes behind leader John Senden. Nitties shot 77.
