It was an injury concern no one wanted just days out from tackling Honduras.
Juric joined Tim Cahill in training with sneakers on Wednesday (AEDT), sparking fears the Socceroos might miss the beanpole striker for the World Cup qualifier.
Surely Australia weren't about to be robbed of another top talent - with Mark Milligan, Mat Leckie (suspension) and Robbie Kruse (knee) not partaking in the first leg and Cahill under an injury cloud?
As it turns out, Juric had a most reasonable and relieving excuse.
"They lost my bags," Juric laughed.
Like all of the Socceroos, Juric endured a horrible transit to San Pedro Sula, taking three flights from Switzerland to Central America, losing his bags on the way.
But he's since been reunited with his luggage, and with them, his size 11 boots.
"It got in last night ... nothing's missing," he said.
"I can join in training today which will be good."
The 26-year-old scored in a 90-minute appearance for Luzern on Monday (AEDT) and says he's ready to back up in a very different climate.
"I've been prepping for it as well, doing a lot of heat adjusting in the sauna," he said.
"It's cold in Switzerland now. If I just came in here it would be a bit of a shock to the system. It's just to keep it on level terms.
"After training I try to get a good 10, 15 minutes in. I'm not a big fan of the sauna. I do it because it will help a little bit.
"Just that little bit for that one per cent maybe. If it helps, it helps."
Australia's first choice striker has scored six goals for his club and once for the Socceroos - the breakthrough goal in Melbourne against Thailand - this year.
But his club fortunes have been poor. Luzern were bottom of the table until the weekend's result.
He hopes his Socceroos spell will bring mental freshness to take back to Switzerland - and a place at the World Cup.
"Every time I come here I love it. There's nothing better for me. The team environment we have, it's second to none," he said.
