Fabian Schar has revealed he "can't remember anything" after an opposition player was forced to intervene to prevent him from swallowing his tongue.
Schar was involved in a sickening clash of heads with Jemal Tabidze midway through the first half of Switzerland's 2-0 Euro 2020 qualifying win against Georgia in Tbilisi.
The Newcastle defender was knocked unconscious by the collision and lay prone in the penalty area before Georgia midfielder Jano Ananidze reacted.
Ananidze realised the danger Schar was in and raced to the 27-year-old, inserting his hand into the defender's mouth to ensure that he did not swallow his tongue.

But he admitted the incident had taken its toll.
"It looks awful, I can't remember anything," Schar told Swiss newspaper Blick having watched the footage back.

He was eventually substituted in the 62nd minute.
