Turkish referee Cüneyt Çakır has left hospital after being treated for a lung problem.

The experienced referee had to be taken to hospital after suffering a pneumothorax during last weekend’s Super Leauge match between Gençlerbirliği and Karabükspor.

Çakır’s doctor Tevfik Ali Küçükbaş said, “Due to an unexpected airflow in his lung tissue, there was an accumulation of air in his chest. This prevented his lungs from enlarging in order to breath properly.”

The World Cup referee spent four days in hospital and is expected to return to training in 7-10 days.

Upon leaving Çakır thanked the TFF and the hospital staff for their help and support.

Çakır became the first Turkish referee in 40 years to officiate at a World Cup. He officiated three games in Brazil, including the semifinal match between the Netherlands and Argentina.
