Atletico Madrid striker Moussa Dembele fainted and appeared to lose consciousness during a training session on Tuesday.
The former Lyon striker was filmed stretching out his hamstrings before falling to the ground and lying motionless on the pitch.
Dembele’s teammates were quick to react and assisted the striker before calling for the help of Atletico's medical staff.
Members of the medical team spent several minutes trying to resuscitate the player, while others ran to the pitch side ambulance to request the paramedic and a stretcher.
Thankfully, the 24-year-old regained consciousness after being turned on his side and was able to leave the pitch unassisted.
Dembele has since gone for medical tests following the worrying episode and reports have stated there is no 'serious' concern, claiming the incident was caused by low blood pressure.
As a result, Dembele was able to drive himself home following the incident in the Spanish capital.
The dramatic scene at Atletico brought back memories of the moment Fabrice Muamba collapsed on the pitch with a suspected heart attack in 2012.
Howard Webb abandoned Tottenham's FA Cup quarter-final against Bolton, saying the players 'could not go on' after Muamba collapsed.
Muamba fell to the ground on his own near the centre circle when the game was 41 minutes old and players soon had tears in their eyes as the severity of the situation quickly became clear.
Several looked to the skies in prayer and were consoled by team-mates as medics attempted to resuscitate Muamba with electric shock treatment.
Muamba did recover from the cardiac arrest, despite his heart having stopped for 78 minutes.
Dembele joined Atletico on a 'loan with an option to buy' deal from Lyon in January and was subsequently handed the No 19 shirt, which was previously worn by Diego Costa.
However, he has struggled to cement his place in the team - making just two LaLiga appearances so far.
However, Diego Simeone is willing to give the striker more opportunities to prove himself, according to Marca.
