Nigeria footballer Taiwo Awoniyi was rushed to the hospital after suffering a head injury during a Bundesliga game between Mainz 05 and Augsburg.
The 22-year-old collided his head against that of Augsburg defender Uduokhai during an aerial challenge.
The young striker suffered a concussion and immediately fell unconscious, with referee Marco Fritz quickly moving to his aid.
Photos from the game showed the Bundesliga referee helping Awoniyi and preventing him from swallowing his own tongue.
The incident caused a stop in play for some minutes, with the medics moving in to revive the Mainz forward.
Awoniyi was then stretchered off and immediately taken to the hospital to receive further treatment.
“Our striker Taiwo #Awoniyi suffered a concussion in his collision with @FCA_World’s Felix #Uduokhai and is spending the night in hospital as a precautionary measure. Get well soon, Taiwo,” the club tweeted.
Meanwhile, Mainz manager Achim Beierlorzer later revealed that the player has gained consciousness and is stable.
“We have received the all-clear from the doctors. Awoniyi is conscious again, can remember the things that happened. He had a severe concussion and had to stay in the hospital for observation,” he said.
