BRASILIA, Oct 8 (Reuters) - Brazilian right-wing Senator Flavio Bolsonaro said on Thursday he had nabbed the endorsement of author-psychiatrist Augusto Cury, who ranked third in Sunday's first-round election, for the October 25 runoff against leftist President Luiz Inacio Lula da Silva.
• Bolsonaro shared a video on social media of Cury announcing the endorsement, following local media reports of Cury's support
• Cury, from the Avante party, received 2.89% of the valid votes - which exclude blank and null ballots - in the first round
• Cury has avoided identifying with either the political left or right, instead campaigning under the slogan "Centered on what matters"
• Also among the top five finishers, Ronaldo Caiado endorsed Bolsonaro earlier this week, while Renan Santos said he will not endorse either of the two candidates
• Bolsonaro, son of former President Jair Bolsonaro, exceeded expectations in the first-round vote with a slight lead over Lula - 47.03% vs 45.16%
