The athletic Western Australian had just made his reserves debut on Saturday, having dealt with minor shoulder and quad issues during the pre-season.
Jones was nearing an AFL debut, with coach Adam Kinglsey expecting to add the 19-year-old small forward into his high-pressure 'Orange Tsunami' gameplan in the coming rounds.
Giants GM of Football Jason McCartney confirmed the news of Jones' injury on Tuesday.
"It's really bad luck for Darcy," said McCartney.
"Unfortunately it's just one of those things that happen in football and we'll wrap our arms around Darcy and give him all the support he needs at this tough time.
"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."
