The 29-year-old has been a Hawk since 2011 and played in their triple premiership run between 2013-2015, but hasn’t had anywhere near the same impact so far this season.
The goalsneak has only managed 14 goals from his 13 matches so far this season, and is on track for his lowest goal tally since 2014.
Puopolo is also averaging just 12.4 disposals (his lowest total since 2012), and a career-low of 1.5 marks per game.
Lyon says he’s heard whispers regarding Puopolo’s future and has been told the Giants are quite keen on the Hawk’s services, in what could be a move to help the small forward turn around his poor form.
“He gives [the Giants] that blue-collar hard nose,” Lyon told SEN Breakfast on Tuesday morning.
The Giants still won’t be in the box seat for Puopolo at the end of the season, as he is contracted until the end of 2018, meaning the two clubs will need to work out a trade should GWS want their man.
Puopolo could fill the void of outgoing Giants forward Steve Johnson, as the 34-year-old is out of contract at season’s end, with 2017 set to be his last.
