Robert Allenby has withdrawn from the Canadian Open after splitting with his caddie in the middle of the first round, with a fan carrying his bag the rest of the way.

Allenby shot a 9-over 81 Thursday at Glen Abbey Golf Club and finished his round with the fan on his bag because, according to Canadian golf outlet Score Golf, Allenby and caddie Mick Middlemo had a blow-up over club selection.

Score Golf reported that Allenby and Middlemo got into a heated exchange at the 13th hole, the Australian's fourth of the day, and at the 18th the caddie walked off the course.

Earlier this year, Allenby was involved in a strange off-course incident in Hawaii. In January, after missing the cut at the Sony Open, Allenby said he was robbed and beaten and needed help from a homeless woman.
