“Tom Rogic will be out probably for the next few months,” Rogers said at a media conference on Thursday.
“He had to have an operation. It was unfortunate, it was right at the end of training, the same spot where he had it before.
“His foot stuck in the ground and he did a full twist on it.
Bad news coming in today, Tom Rogic out for a few months. Get back to fit as soon as possible 🙏🏼🍀 pic.twitter.com/9JC3tghpIR— Celtic Info 🍀 (@Celtic_Info) February 9, 2017
"It was either going through the same procedure as before or have an operation so he went to London for an operation and it is all done and he is on the way to recovery now.
“It is a big disappointment because he is a player I was looking forward to seeing back.
“He will be back for the end of the season, it is a disappointment that he will miss up to eight weeks.”
Rogic was spotted this week heavily strapped and on crutches on his way to the operation.
The good news is the Canberra-born Rogic may be available for the Caltex Socceroos' World Cup qualifier with Saudi Arabia on June 8 in Adelaide.
But for the clashes with the Iraqis away on March 23 and UAE in Sydney on March 28, the 24-year-old will be missing.
