Colombia's Juan Zuniga kneed Neymar in the back in Brazil's 2-1 quarter-final victory, ruling him out of the tournament.
"I won't say he came to injure me, I don't
know what was going on in his head but
everyone who understands football can see that it wasn't a normal challenge," Neymar said.
"When you want to foul someone to stop a
game or stop a counter-attack, you kick their ankles, you push, you pull, but the way the ball was falling, it wasn't a normal game situation.
"Many of you say I am a diver and I don't
care that you say that.
I can defend myself when I can see what's going on around me.
"But I can't defend myself from what comes from behind.
What defends me in that situation is the rules and I couldn't defend myself from that and I was injured.
"God blessed me," a tearful Neymar added.
"If it had been another two centimetres I could be in a wheelchair today."
Neymar said Zuniga called him the next day to apologise but he stopped short of forgiving his rival for the challenge.
"I don't hate him, I don't hold a grudge,"
Neymar said. "But I don't feel anything."
