The English FA Cup match between "Wrexham" and "Sheffield United" clubs became famous not because of the final score (3:3) or stunning goals.

In the second half of the match, referee Dean Whitestone decided to expel the guest player Daniel Jebbison from the field, showing him an unusual card near his nose.

Television viewers immediately noticed that the referee was holding a circular red card in his hand.

After the match, fans received an explanation from experts as to why this happened.

It is said that different shapes of yellow and red cards are beneficial for players who have difficulty distinguishing colors, and referees can quickly grab the necessary card from the pocket.
