Luis Suarez Apology -- ADMITS Biting Giorgio Chiellini in World Cup Match

Uruguay superstar Luis Suarez is changing his story AGAIN -- and now ADMITS he bit Italian player Giorgio Chiellini during a World Cup match last week.

Initially, Suarez insisted there was NO BITE -- despite strong video evidence -- saying he simply lost his balance and accidentally hit his face against Chiellini's shoulder.

But now -- after FIFA banned him for 4 months -- it seems Suarez has finally come to his senses ... because he just issued the following statement on his Twitter page:

"After several days of being home with my family, I have had the opportunity to regain my calm and reflect about the reality of what occurred during the Italy-Uruguay match on 24 June 2014.

Independant from the fallout and the contradicting declarations that have surfaced during these past days, all of which have been without the intention of interfering with the good performance of my national team, the truth is that my colleague Giorgio Chiellini suffered the physical result of a bite in the collision he suffered with me. For this:

- I deeply regret what occurred
- I apologize to Giorgio Chiellini and the entire football family
- I vow to the public that there will never again be another incident like."
