He was selected with the Brisbane Lions' first selection (pick 5 overall) in the 2010 national draft from SANFL club, Woodville-West Torrens.
Of Polish descent, Polec is an outside midfielder who, prior to being drafted, played senior football with Woodville West Torrens and was a key player in their 2010 finals series. Woodville-West Torrens coach Michael Godden described Polec as being "as good a junior as I've seen come through the system" and praised him for his skill, composure and work ethic.
Brisbane Lions (2011–2013)Edit
Polec was selected in the initial extended squad for the Lions in round 2 in the 2011 season, but was left out of the final team. He made his AFL debut against Melbourne in round 3. In his first three seasons at Brisbane, he played in sixteen games. In September 2013, Polec requested a trade to a South Australian team, and in October, he nominated Port Adelaide as his preferred club of destination.
Port Adelaide (2014–2018)Edit
Polec officially joined Port Adelaide in October 2013. Polec had an immediate impact at Port Adelaide, achieving a career-high thirty disposals in round 7 against Greater Western Sydney.
2015 was not to be for Polec, suffering a stress reaction in his foot which developed into a navicular fracture, forcing him out for the season. In early 2016, scans cleared Polec of the fracture and he was declared fit to resume full training. On 13 September 2018, Polec advised Port Adelaide that he wished to be traded to North Melbourne.
North Melbourne (2019–present)Edit
Polec was officially traded to North Melbourne, along with teammate Jasper Pittard, in October 2018.
