WITHIN minutes of the announcement of Dom Cassisi's retirement, Port Adelaide supporters had flooded social media with tributes for the four-time Fos Williams Medallist.

It's no surprise the tributes have flooded in, given the popularity of Cassisi among the players and supporters alike.

He approached the game in the the true Port Adelaide way - tough and determined.

Supporters will have the chance to farewell Cassisi at Sunday's game against Melbourne at Adelaide Oval.
