SAO GONCALO, Brazil -- An apparent seizure kept Paulo Filho out of his scheduled fight in Brazil on Sunday night.

Filho, a former WEC middleweight champion and PRIDE veteran, was supposed to take on UFC veteran Amilcar Alves in the Fatality Arena 7 main event in Sao Goncalo, but was pulled from the bout hours before the fight.

According to Osiris Maia, member of the Brazilian Mixed Martial Arts Confederation (CBMMA), Filho suffered a seizure.

"Paulo was apparently hospitalized this morning after suffering a seizure. We can’t let him fight after that," Maia told MMAFighting.com.

Filho hasn’t fought since a decision loss to Andre Muniz in February. Once considered one of the best 185-pounders in the world, the Brazilian has gone 1-4-2 over his past seven bouts.

UPDATE: Despite his fight being scratched from Fatality Arena 7 on Sunday, Amilcar Alves received his show money, according to his manager Andre Pederneiras. Paulo Filho won't receive his money, sources told MMAFighting.com.
