U-20 player punches himself

Thanks to Ed Rae for spotting this unusual attempt at trickery.

Read the brief story and view the clip. Is there something out of balance here? The Chilean player Carrasco was feigning being punched in an effort to get his opponent dismissed from the game. Should Carrasco therefore be dismissed for this act?
