Cahill suffered an ankle injury in Melbourne City's 1-0 loss to Sydney FC at AAMI Park on Friday night.

He was substituted immediately and sent to hospital for scans, and there were fears he would miss the trip to Honduras all together. 

While the 37-year-old left for San Pedro Sula on Monday, it remains to be seen if he features in the World Cup play-off first leg. 

“I’m not promising anything, but this is a massive opportunity for us, the chance to go to a fourth consecutive World Cup,” he said. “We’ve made a calculated decision — if it works, fantastic.

“I’ve had 20 years of experience of injuries at the highest level, and you can speed processes up with round the clock work. On the plane I’ll have my own ice machine.

“It’s not my call but I wouldn’t put myself in any danger of harming myself.

“It’s a massive two weeks for Australian soccer, but I wouldn’t be doing it if I thought it was the wrong thing.

“I’ll give it a go but if not I want to be in the trenches with my teammates. I was on the phone the other day talking to Mile Jedinak about what it was like in Uruguay (in 2005).

“It’ll be a real eye-opener for the guys in the squad, it’ll be difficult for them having not been in this situation before.”
