Hubbard badly hurt her elbow during her attempt to lift 132kg in the women's +90kg final on the Gold Coast and had to withdraw from the competition.
Hubbard, who is transgender, had attracted some controversy for her inclusion in the event.
Today she said she had seen medical staff and her arm was "busted".
"It could be career-ending."
Of her decision to lift the heavier weight she said: "You can't just phone it in."
Coach Simon Kent said Hubbard had completely ruptured a ligament.
