Because the referee has given Defoe a yellow card and under the pathetic FA rules on retrospective punishment no further action can be taken, where as with Suarez - he wasnt booked and because no punishment was taken, he can get the ban.
Its the FA rules that need changing, pathetic that you...
Were not really missing out on much in that case anyway !!!
Not really as Evra, Welbeck or Defoe dont have previous history of racism or biting opposition players......
