Linda Caicedo, 18, Female Columbian Footballer Collapese

World Cup star, 18, grabs her chest and collapses at training in Sydney before being rushed to hospital in an ambulance after losing consciousness

Breakout World Cup star Linda Caicedo may not feature again in the tournament after the Colombian collapsed at training in distressing scenes that were caught on video.

The young gun, 18, was rushed to hospital and was unconscious for at least 90 seconds as medics and terrified team-mates rushed to her aid at the team's base in Sydney.

Footage shows the star jogging with teammates before she suddenly stops, clutches her chest and falls to the ground.

Concerned players gather around her before a woman who appears to be a member of the training staff sprints to the scene, closely followed by other team staffers, one of whom was carrying a kit bag.
