GWS have pulled off a huge signing on the eve of the AFL season, locking in midfield bull Tom Green to a new four-year contract.

Green, 22, appeared set to head into the campaign without a contract for next year but instead opted to take the long-term deal that keeps him at the club until the end of 2027.
