He missed the entire 2011 season, while he managed just three games in 2014 due to persistent shoulder injuries.
The 2010 premiership player was then dropped after Round 6 this season, but was recalled to the side in Round 14. He enjoyed a return to form in the back half of the year, playing the final 10 games of the season
Brown, who is the twin brother of West Coast defender, Mitch, could cover the loss of veteran backman, Michael Firrito, who was recently delisted by the Kangaroos.
