Nick Coughlan is delisted by St Kilda after not managing to play a game for the club while struggling with hamstring and foot injuries in 2017.
At 193cm, the No. 23 selection in the 2015 rookie draft showed promise with his intercept marking.
He managed just seven matches for Sandringham this season, plus one in the Development League.
"Nick displayed a high level of professionalism in his time at the Saints. We thank him for his contribution to the club and wish him well in his future endeavours," Saints chief operating officer Ameet Bains said.
