Speaking to Australia's Channel 10, Montemurro explained: "I think there were some complications and I've only caught up with the scenario in the last 24 hours. There was a subsequent intervention, but I do believe she is now back running. I think it was something completely different [to the ACL injury]. I think the knee is fine. I think there was some other issues, but again I've only been briefed in the last 24 hours."
