Swans star Isaac Heeney has suffered a broken thumb during a training mishap earlier this week.

The 23-year old will undergo surgery on Thursday, however, the club is confident he will be available to play round one.

He is expected to return to training within days.

โ€œIsaac was struck awkwardly on the hand in a fairly routine contest during training on Monday. It was just one of those unfortunate incidents that can happen at training,โ€ Gardiner toldย sydneyswans.com.au.ย 

โ€œScans confirmed a fracture in his thumb so he will undergo surgery tomorrow to repair the break.

โ€œIsaac is obviously disappointed but he should be back running in a matter of days and weโ€™re confident he will be available for the start of the season.โ€

Heeney is coming off a strong 2019 season where he averaged 20.1 disposals, 5.7 marks and 3.7 tackles and booted 26 goals from his 22 matches.
