World Cup 2014: FIFA Analysing Neymar Injury Incident

FIFA could take action against Colombia's Juan Zuniga for the World Cup quarter-final challenge that left Brazilian superstar Neymar with a fractured vertebrae, a spokeswoman said Saturday.

"The FIFA Disciplinary Committee is analysing all the elements provided, the videos and the match reports, and will decide whether or not to take action," FIFA spokeswoman Delia Fischer told a briefing.

Neymar was injured in Brazil's 2-1 win over Colombia on Friday when Zuniga kneed him in the back. The Barcelona forward will miss the rest of the World Cup.

Zuniga, who plays for Napoli in Italy, has denied he intentionally sought to hurt the 22-year-old Brazilian. (Death Threats, Racist Abuse for Juan Zuniga Over Neymar Foul)

"When I'm on the field I always do what I have to, to defend my country and the shirt I wear, but always without intent to injure anybody," Zuniga told Brazilian television after the game.

"This was a game that everyone wanted to win so it was hot." (Related: Brazilian press urges team to play for Neymar)

Former World Cup winners Ronaldo of Brazil and Italy's Fabio Cannavaro appeared at the daily FIFA briefing where the Neymar injury dominated debate.

"The injury was very violent," said Ronaldo. "I believe there was an intention to hurt by the player. I believe it was very aggressive and very violent."

Cannavaro agreed.

"I believe that it was a situation which could have been avoided," he said. (Read: Neymar has been hunted, says Scolari)

"I didn't like that very high knee. That leads me to believe it was a foul with a prior intention to cause harm. It didn't give me a very good impression. It's a very evident foul," the Italian added. (Also read: Youthful Neymar carried hopes of a nation)
