PFA chief executive Gordon Taylor has blasted Tottenham Hotspur for allowing Hugo Lloris to continue playing against Everton on Sunday despite being knocked unconscious.
The France goalkeeper came out to challenge Romelu Lukaku during their 0-0 draw at Goodison Park and received a nasty blow to the head, but insisted on continuing the game, with manager Andre Villas-Boas also backing the 26-year-old's decision.
The move has resulted in Spurs being on the receiving end of widespread criticism, with Taylor the latest to complain about the result of the incident.
"I watched the incident on television and I was surprised, to say the least, that he was allowed to stay on," Taylor told the press.
"We are very concerned that the protocol that involves concussed players was not adhered to and I have raised this at the meeting with the professional game's stakeholders and the decision was taken to remind all clubs of the protocol.
"Managers should not take these decisions in the heat of the moment and that needs reinforcing."
Spurs have since confirmed that Lloris has been given the all-clear after undergoing a head scan on Sunday night.
