The former Bolton defender was taken off on a stretcher after sustaining the injury in last Saturday's 3-0 defeat to Bury.
While Hunt admits it is a blow to be injured so early into the campaign, he is glad his absence should only be for weeks, rather than months.
Speaking to Press Association Sport, Hunt said: "The specialist said before (I'll be out for) four-to-six weeks.
"I've done my medial tendon, my MCL, and I've done some damage behind the knee cap. It's like two or three injuries in one but not as serious as first thought."
Nevertheless, the injury comes with the season still in its embryonic stages with Hunt keen to make an impression after signing on with Stanley during the summer.
"It's incredibly frustrating for me," he added.
"I was fit all the way through pre-season, felt really good; it was just about getting the games in early doors but it took three games and I got a knee injury from it.
"For me, it's extremely disappointing but it could have been a lot worse. Hopefully I'll be back end of September, early October."
