Essendon, Carlton to unveil mature-aged debutants in Round 3 By 2021-04-01T15:41+11:00 Essendon pre-season supplementary selection Alec Waterman will make his debut against St Kilda on Saturday, according to AFL Media’s Callum Twomey. The 24-year-old, who was handed a second chance at AFL level after being delisted by West Coast in 2016, will play his first senior game after strong pre-season and VFL practice match form. The Bombers were hit with a triple injury blow this week with Jye Caldwell (hamstring), Sam Draper (ankle) and Dylan Shiel (knee) all set to spend a considerable time of the sidelines, opening the door for Waterman's selection.
