The 24-year-old received the punishment after an independent commission found him guilty of misconduct by using insulting words to Patrice Evra which included a reference to the Manchester United defender's colour.
He had been given the full support of the club, who insist the player is not a racist, and now his team-mates have followed suit.
"Luis Suarez is our team-mate and our friend and as a group of players we are shocked and angered that he has been found guilty by the FA," said a joint statement by the squad.
"We totally support Luis and we want the world to know that. We know he is not racist.
"We are a squad of many different nationalities and backgrounds. All of us support the club's commitment to fighting racism. All of us accept there is no place in the game for any form of discrimination."
