Despite a season where Amon is amassing career-high averages for tackles, inside 50s, clearances and contested possessions, Power coach Ken Hinkley opted to exclude the 2021 All-Australian squad member from his 22-man side to face West Coast on Saturday.
The timing of the cut-throat call adds to the intrigue, with the Power understood to be keen on re-signing Amon beyond the expiry of his deal this year.
Amon inked a three-year extension in 2019, turning down reported interest from Victorian clubs to remain at Alberton.
With that contract now nearing its cessation, another call will need to be made by the East Sandringham product who is tipped to receive another wave of interest from clubs in his home state.
According to The Herald Sun, clubs have already begun to express their interest in Amon's services so far this season, with more sides potentially queuing up following the Power's surprise selection call.
Deals as long as four years could be tabled for the Power gun, with clubs not required to offer any player or draft capital given his listing as an unrestricted free agent.
