The controversial football called Suarez has decided to use his mouth as a tool in playing football. He was spotted seriously biting Chelsea defender Branislav Ivanovic during the 2-2 tie at Anfield. The interesting part is that, the referees didn’t see anything wrong with it and so allowed the game to continue without giving him red card for the act.

How can a referee allow the player to be on the pitch after this incident. My question is, has the rules in football changed? If has changed then players should get ready for more biting in football matches.
