The Bayer Leverkusen player fainted on the bench around the 70th minute, after being replaced at the break of the friendly that faced his club with Wuppertaler.As reported by the German club, the player suffered a circulatory collapse from exhaustion. The Leverkusen doctors quickly covered him with blankets. Luckily, he is out of danger, since he was resuscitated and immediately transferred to the hospital.One of the possible reasons that caused the fainting of Bellarabi have been the high temperatures recorded in Wuppertal. At eight o'clock in the afternoon, according to the average German Bild, thermometers marked 33 degrees.Sports director Rudi Voller confirmed to the German newspaper that the player was able to regain consciousness and that he hopes "it is not something serious". In the Twitter account of Leverkusen it has been announced that everything has been left in a fright and that the doctors have given their approval. Even so, he will spend the night under observation.
