Crystal Palace boss Alan Pardew felt his side had been treated harshly by the match officials after the Eagles had a goal disallowed in debatable circumstances in their 1-1 draw at Everton.
Palace were left questioning the call from referee Jon Moss after his assistant's flag went up when Damien Delaney converted a second-half header from Joel Ward's cross, five minutes after Christian Benteke's equaliser for the visitors.
As Ward's delivery was made, Delaney appeared to be onside, with James Tomkins off but not really involved.
James McArthur, standing in front of goal did appear offside as Delaney then headed it, but he did not touch the ball and it was questionable whether his position or movement put off goalkeeper Maarten Stekelenburg.
