Australian Open qualifying has been thrown into disarray as Melbourne's air quality from bushfires continues to cause havoc among players, with Canadian Eugenie Bouchard the latest to succumb to the conditions.
Jakupovic received medical treatment several times throughout the match after complaining of breathing difficulties in the first set.
Australian Open practice was temporarily suspended on Tuesday due to poor air quality as bushfires continued to rage across the country.
The umpire said the conditions were behind the call to stop play after nearly two and a half hours.
Play eventually got underway at 11am - an hour later than scheduled - after the city's air was the worst quality in the world overnight because of the bushfires in the state's east.
Smoke from the East Gippsland bushfires has drifted across Victoria reaching Melbourne prompting health warnings.
It's an obvious concern with the world's eyes set to be glued on Melbourne during the two-week championship from Monday.
"Conditions onsite are improving and are being constantly monitored", the tournament said in a statement.
Organisers said further decisions on match scheduling would be made using onsite data and in close consultation with its medical team, the Bureau of Meteorology, and scientists from the Environmental Protection Agency in Victoria state.
"This is a new experience for all of us in how we manage air quality, so we have to listen to the experts", Tiley said.
Health authorities expect the air quality to bounce between the "very poor to hazardous range" until at least Wednesday night.
TA chief operating officer Tom Larner said any smoke stoppages would be treated in the same way as an extreme heat or rain delay.
"Avoid being outside in the smoke or dust".
Earlier on Tuesday, the EPA's website crashed after receiving a "significant amount of traffic".
