Lúcio Carlos Cajueiro Souza (born 20 June 1979), commonly known as Lúcio, is a Brazilian former professional footballer.[1]
Lúcio was born in Olinda, Recife, Pernambuco. In his career he played for clubs like Unibol (1997–1999), São Bento, Gama and XV de Piracicaba (2000–2001), Ituano and São Caetano (2002), Palmeiras (2003–2006) and São Paulo (2006). In January 2007, he was signed by Bundesliga club Hertha BSC.
In September 2007, he suffered a knee injury which threatened to end his career. He was ruled him for the rest of the 2007–08 season, and most of the 2008–09 season. After almost a year and a half, he was finally able to play again, making a late appearance in Hertha's UEFA Cup match against Olympiacos. However, Lúcio was unable to reestablish himself in the team and on 18 August 2009, Hertha loaned him to Gremio. In July 2010 he moved to Grêmio on a free transfer from Hertha BSC.
