GWS first-round draft pick Darcy Jones is set to miss the remainder of the season after suffering a torn ACL.
The 19-year-old West Australian, taken with pick 21 of the most recent AFL national draft, incurred the knee injury while playing in the VFL on Saturday.
The Giants confirmed the prognosis on Tuesday morning and Jones will meet with a surgeon this week.
"Unfortunately it's just one of those things that happens in football and we'll wrap our arms around Darcy and give him all the support he needs at this tough time," said Giants football GM Jason McCartney.
"He's made a great impression on our group already in the short time he's been at the club. He's a wonderful person and he'll be a great player for our football club."
Small forward Jones has yet to make his senior debut and was one of three players drafted by the Giants in the first round last year, alongside academy selection Harry Rowston and top pick Aaron Cadman.
