RIO DE JANEIRO -- FIFA will be advised on Monday that a neo-Nazi sympathizer invaded the pitch during the Germany-Ghana match.
The fans' anti-discrimination network, Fare, says it is preparing a report on Saturday's incident, when a shirtless fan interrupted play.

Slogans written on his chest and back included "HH," signifying Heil Hitler, and "SS," referring to the Nazi paramilitary unit.
Fare executive director Piara Powar tells The Associated Press "there would be no other explanation for it."
Powar says Fare's report will also refer to fans wearing blackface makeup at the match in Fortaleza with no intervention by stadium security.
FIFA says both incidents "are currently being analysed" by its disciplinary committee.
Earlier Sunday, FIFA spokeswoman Delia Fischer told reporters: "We do not respect any discriminatory messages."
FIFA holds national football federations responsible for their fans' behaviour inside stadiums.
In a second incident, a man ran onto the pitch in the second half of the 2-2 draw.
The shirtless fan had an email address and telephone number written on his back. He was ushered away by Ghana midfielder Sulley Muntari before being detained by stewards.
Brazil's organising committee spokesman Saint-Clair Milesi said the man was reportedly from Poland.
"He came running, charged and jumped over the stewards," Milesi said. "Such behaviour is totally unacceptable. He was taken to the local authorities for the proper measures."
