O'Brien Collingwood rift Harry O'Brien: Will he be back in time for training on Monday? Collingwood will meet disgruntled star Harry O'Brien on Sunday, with uncertainty over whether he will return to the club. There is speculation O'Brien and Buckley fell out through the week, with the pair exchanging words during a meeting. O'Brien, also nursing an ankle injury, flew to Port Douglas on Friday, and is due to return on Sunday. The Magpies had said O'Brien was also due to return to training on Monday but Buckley, who has refused to elaborate on the incident, said that was uncertain. Asked if the premiership defender would definitely return to the club on Monday, Buckley said: "No, not definitely. But we'll resume normal planning. We will catch him on Sunday and we'll go from there. In explaining why O'Brien had headed north, an unusual move for an injured player requiring treatment, Buckley on Saturday told Triple M: "The doctor has confirmed Harry had floating bone from an injury sustained two or three weeks ago. He was unavailable for selection for the match committee due to the doctor's call and, after that, we spoke to 'H' and 'H' chose and we agreed on, giving him a couple of days off. He shot off for a couple of days and he will back tomorrow afternoon and then we'll resume normal planning. O'Brien had been in good form before last week's events. The Magpies' stunning 41-point win over Carlton on Friday night could mean O'Brien finds it difficult to reclaim his spot for Friday night's clash against Adelaide - should he be fit and available for selection.
