Who was the first player to be dismissed (receive a red card) in an FA Cup Final?

The 1985 FA Cup Final was the 104th final of the FA Cup. It took place on 18 May 1985 at Wembley Stadium, and was contested by Manchester United and holders Everton. United won by a single goal, scored in extra time by Norman Whiteside, when he curled the ball into the net past the reach of Neville Southall after a run from the right.

Late in the second half, Kevin Moran of Manchester United was sent off for a professional foul on Peter Reid, who was clean through on goal. He became the first player to be dismissed in an FA Cup Final. Television cameras revealed that he had gone for the ball, and not for Peter Reid in the offending tackle. He was later presented with the winner's medal that had at first been withheld. Had Everton won the match they would have completed an unprecedented Treble of League, FA Cup and European Cup Winners' Cup.
