Young Crow Sam Siggins has undergone successful wrist surgery.

Siggins, 20, had surgery on Thursday to repair a wrist injury that has plagued him for much of the season. The Tasmanian is expected to be ready for the start of pre-season training.

A developing key defender, Siggins played 17 of Adelaide’s 18 SANFL games this year. He was recruited with pick No.62 in the 2012 National Draft and is yet to make his debut.
