The former West Coast Eagles recruit has been a consistent performer since arriving at the kennel, averaging 18 possessions in 38 games in the red, white and blue.
With one round remaining in 2014, the 23-year-old is ranked fourth in total goals, sixth in marks and ninth in possessions at the Club.
“Koby has impressed since arriving at the Club with his competiveness and versatility,” List Manager Jason McCartney said.
“He has adapted well to the various roles he has played and we are really starting to see him mature right in front of our eyes.”
Stevens will line up in his 50th career game against GWS Giants after being drafted at pick 22 in the 2009 National Draft.
