FIFA's chief medical officer professor Jiri Dvorak has claimed that Tottenham Hotspur goalkeeper Hugo Lloris should have been immediately taken off the field following a blow to his head.
The Frenchman was knocked unconscious after connecting with Romelu Lukaku's knee during yesterday's goalless draw with Everton at Goodison Park.
After seeking treatment, Lloris was permitted by manager Andre Villas-Boas to stay on the pitch and finish the game.
"The player should have been substituted," BBC Sport quotes Dvorak as saying.
"The fact the other player needed ice on his knee means it's obvious the blow was extensive."
Brain injury charity Headway have criticised Tottenham for allowing Lloris to play on.
