The Portuguese coach has now apologised to Taylor - but not to the referee or to Diarra.
Queiroz said: "I am deeply sorry if my comments, made when emotions were running high after the Portsmouth game, were misconstrued.
"All I sought to say was that in the modern game, because of its speed, we need to have more vigilance on mistimed tackles. I apologise for any upset my remarks may have caused."
Queiroz had accused Diarra of elbowing Cristiano Ronaldo, and the referee allowing him to use over-physical tactics against the winger for the rest of the game.
