Linda Caicedo is fast becoming the biggest story of the biggest Women's World Cup to date.
Her stunning goal to set up Colombia's shock 2-1 win on Sunday over Germany, one of the tournament favourites, was the latest magical moment from the 18-year-old Real Madrid forward.
But her performances on the field have been dimmed for some by concerns about her health.
The goal against Germany was even more remarkable considering there were doubts Caicedo, who recovered after being diagnosed with ovarian cancer at age 15, would be able to play after an episode in training earlier in the week.
In a video released by Colombian media outlet DSPORT, she was seen holding her chest and then voluntarily going to the ground.
Head coach Nelson Abada said it was a culmination of stress and fatigue, adding there was no problem. There was a similar explanation on Sunday after another incident involving Caicedo.
There'd been no signs of lingering effects when she stepped around two German defenders in the 52nd minute and lashed a shot into the top corner for one of the goals of the tournament so far.
But then, in the 83rd, she dropped to her knees behind the play before lying face down on the grass as Colombia's medical staff went to her aid.
Scenes like this are extremely rare in soccer's top flight.
And given the World Cup is being held during the winter months in Australia and New Zealand, excessively high temperatures cannot be blamed. The evening temperatures in Sydney have been around 57 degrees Fahrenheit (14 Celsius).
Again, Colombia's staff dismissed concerns about the teenager's health.
We know that Linda had some problems in the past, but nothing to be worried about, assistant coach Angelo Marsiglia said.
She was very tired of course. She had a bit of acceleration in her heart, but this wasn't a problem.
Caicedo continued to play after receiving on-field assistance on Sunday night before being substituted off in stoppage time, with Marsiglia saying she was exhausted.
With a goal in each of her opening two games at the tournament, Caicedo is rising to expectations at her first World Cup. She is showing no signs of being weighed down by her billing as one of the brightest talents in women's soccer.
With more eyes than ever on the tournament, there will be greater scrutiny of her health as the competition progresses. Any more obvious episodes of fatigue or exhaustion are likely to raise welfare concerns.
Player health and injury recovery at the Women's World Cup ultimately comes down to the medical staff of each national team.
While FIFA has its own medical team at the World Cup to offer advice as needed, soccer's world governing body said each team's doctor has autonomy and ultimate responsibility for their players.
Caicedo once feared she'd never play high-level soccer again after her cancer diagnosis. At that point, she had already made her debut for the senior national team and pro team Amrica de Cali.
But she recovered and joined Real Madrid in February. Last year she led Colombia's Under-17 squad, who were runners-up at the U-17 Women's World Cup, and also appeared for the Under-20 squad.
In her debut at the senior World Cup, Caicedo also scored in Colombia's 2-0 win over South Korea.
Colombia's second win all but secured the team a spot in the knockout stage. Las Cafeteras will advance unless they lose to Morocco by at least four goals on Thursday and Germany draws or beat South Korea the same day.
