Franjic got injured late in the game in Australia's 2-0 win over the UAE on Tuesday.
Franjic was confident he would be fine to play on Saturday.
"It's nothing too major and we have great medical staff so I'm sure I can get back out there for Saturday," he told reporters after the match.
"It was towards the end of the game so we took precautions and I finished the game on the right wing. I didn't think it was too bad so I continued to push through it.
"I'm sure I will be good for Saturday."
Franjic said that the conditioning regime put in place by Socceroos staff was helping him a lot despite the amount of football he had played.
"I'm holding up good, every game I am getting fitter," he added.
"Working with the conditioning coach and looking at the results I am getting stronger and stronger."
