Sydney is reportedly keeping tabs on former Gold Coast and Fremantle midfielder Harley Bennell, as the 26-year-old tries to get back onto an AFL list.
Bennell was delisted from the Dockers midway through the season, and has since undergone more surgery on his troublesome calf.
However, doctors believe they have rectified Bennell's long-term injury, which could increase his chances of an AFL return.
According to AFL.com.au, Sydney has recently reached out to Bennell, and are looking over his medical history.
Bennell has played 83 matches across his AFL career, although just two of those have come in the past four seasons.
