Darcy, the son of former Bulldog Luke, was drafted to the club with pick two in the 2021 AFL Draft as a father-son selection. The young key forward dealt with a stress fracture in his foot for the opening half of the season, but made his debut in the Dogs' VFL side in Round 8.
While drafted as a key forward, Darcy has played around the ground in his time in the VFL, with stints in the ruck and backline, impressing with his form in the defensive 50.
The 205cm 19-year-old played arguably his best game in last weekend's match against Werribee, collecting 14 marks and 3 inside 50s in the 26-point win.
Western Bulldogs coach Luke Beveridge made the announcement of Darcy's debut at training on Thursday, set to become the third person in his family, after father Luke and grandfather David, to run out in the red, white and blue.
Darcy's inclusion in the team leaves Alex Keath's spot in doubt after the backman was dropped prior to Round 20. Keath also played in Footscray's win over the weekend, collecting 14 touches.
The Bulldogs will face Fremantle at Marvel Stadium on Saturday, set to kick off at 4:35pm (AEST).
