Quiroz, 20, was playing just his fourth league match after being promoted to the first team this season.

After contesting a header with opponent Gabriel Graciani, Quiroz fell hard on the turf.

Falling from quite a height, the defender was unable to put his hands out to protect himself in time.

He subsequently fell head-first into the ground with a sickening thud.

Quiroz required urgent on-field treatment following the awful incident.

He was put in a neck brace by doctors, before being stretchered off the pitch.

The youngster was then replaced by former Liverpool defender Emiliano Insua.

Racing went 1-0 down just five minutes later.

Adrian Emmanuel Martinez put Instituto 1-0 up on 40 minutes, with the home side going in at the break ahead.

Racing managed to fight back from the adversity of losing Quiroz, however, earning a draw in the second half.

Maximiliano Moralez equalised on 72 minutes to see the points shared.

Racing currently sit 16th in the Argentine top flight, with Instituto three places below after 19 matches.
