The news have in fact been confirmed.
UAE Team Emirates' doctor Adrian Rotunno has confirmed the information himself: "Unfortunately Adam Yates has been diagnosed with a concussion after his crash today at the UAE Tour. He is stable with other superficial injuries."
"For the sake of Adam’s health, and as per concussion protocols, he was withdrawn from racing. He will need recovery, and the medical team will continue with neurological monitoring and rehab going forward."
This is set to cause another wave of outrage regarding the safety measures taken within pro cycling races. Another high-level athlete continued to race despite not being physically fit. This has too often been the case over the past few years, recently Stefan Küng's case at the European Championships was the most notable one specially as the Swiss rider kept racing with a broken helmet.
