It is the latest in a long run of injuries for the former Orlando Pirates left-back, who has spent a great deal of his career on the treatment table.
And Hunt believes this latest blow could be the final straw for Thwala.
"He will battle to play football again. He went over his leg in the reserve game against Sundowns last week and broke his ankle; it's very bad. It's going to be tough for him."
Hunt also gave out some mixed news on the SuperSport injury front.
"George Maluleka is out for some time. Davies Nkausu is fine, but Mark Haskins is also out."
