"Gente" magazine photographer Enrique Medina said the attack happened outside Maradona's father's house on Sunday night as he waited to take a picture of the 1986 World Cup winner.
Medina told The Associated Press on Monday that Maradona ran at him "like he was taking a free kick" and kicked him so hard in the groin and upper leg area that he "doubled over in pain."
"This wasn't the kick or an ordinary person," Medina said. "This is from someone used to kicking ... He seemed very angry, out of his mind. Like something had happened in his father's house."
Maradona has often complained that that the media follow him too closely. In 1994, he fired an air gun at reporters and was given a two-year suspended sentence. In May, he stopped his car on a highway and threw rocks at cameramen following him home from the airport.
Maradona is visiting Argentina as he works in Dubai as a global sports ambassador for the Gulf city.
