FIFA: Lloris should have come off
FIFA's chief medical officer has said that Tottenham goalkeeper Hugo Lloris should have been substituted after being knocked unconscious during the match against Everton.
Professor Jiri Dvorak said FIFA's guidelines state that if there is any doubt about concussion then the player should be removed from the field of play.
Dvorak said there was a "99 per cent probability" that Lloris would have been concussed after being knocked out when his head made contact with Romelu Lukaku's knee.
Spurs boss Andre Villas-Boas said he made the call for Lloris to continue, a move which has been criticised as "dangerous" and "irresponsible" by brain injury charity Headway.
FIFA hosted a conference on concussion in sport a year ago, and earlier this year updated its guidelines, which are followed by the FA.
Dvorak said: "The player should have been substituted.
"The fact the other player (Lukaku) needed ice on his knee means it's obvious the blow was extensive.
"It's a 99 per cent probability that losing consciousness in such an event will result in concussion.
"We have a slogan: if there is any doubt, keep the player out."
