This is one for the record books.
Paulão,defender of brazilian club Mogi Mirim got a red card for wearing the same number on his shirt as has team mate Fabio Sanchez.
He was wearing a number 4 shirt in the first half which he inexplicably changed to a number 3 shirt after half time.
The ref gave him a yellow for having the same number as another player.He had already got a yellow in the first half for a non shirt related offence.
So he had to take the long walk out.
His team incidentally went on to lose the game.
