Lincoln was a member of the 1999 Atlético Mineiro team, who were runners-up in Campeonato Brasileiro Série A, a team that also included Marques, Juliano Belletti, Caçapa, Carlos Galván, and the 1999 top-scorer Guilherme, among others.
Lincoln was signed in 2001 by Kaiserslautern as a replacement for playmaker Ciriaco Sforza, who was bought by Bayern Munich. The slender, but technically gifted Lincoln made an immediate impact and contributed to a strong Kaiserslautern finish in that season. However, trouble was afoot within the club from Rhineland-Palatinate: heavy internal friction was experienced and this was not helped by a large turnover of players. The last straw was when Lincoln disappeared in spring 2004; it turned out that he had headed back to his native Brazil as he felt it would be better for an injury he was apparently suffering from. This was not endorsed by the club and earned him a season-long suspension. Many of the club's fans, members of the board, and playing staff were left embittered by the fact that Lincoln left the club while they struggled against relegation.
Lincoln's reputation had suffered and it was seen as a surprise when Schalke 04 signed the playmaker. However, his game flourished while at the Ruhrgebiet club, and he was one of the strongest pillars in the surprising Schalke 2004–05 campaign that earned them second place in the Bundesliga. Although Lincoln experienced a dip in form in 2005–06, he firmly established himself as one of the best playmakers in the Bundesliga.
In June 2007, Lincoln signed a four-year contract for Galatasaray, for a fee of around €5 million. He was greeted at the Ataturk International Airport with a crowd of 5,000 Galatasaray supporters (see: ultrAslan).
Lincoln scored five times in his first season in the 2007–08 Turkcell Süper Lig and he made a few important assists, showing great performances both in domestic play and UEFA Cup games. He became a favorite of the Galatasaray fans. However, he was taken out of the squad of the seventh week clash against the arch-rivals Beşiktaş. Karl-Heinz Feldkamp took Lincoln and teammate Hakan Şükür out of the match squad because they had broken the camp rules by bringing family and friends to training. After the 2–1 win, thanks to the goals of Hakan Balta and Shabani Nonda (penalty), some have called Feldkamp a braveheart and a hero, but many other supporters criticised him because of the decision.
He eventually had the opportunity to play against rivals Fenerbahçe on 9 November 2008 and scored one of the quickest goals ever seen in a Fenerbahçe – Galatasaray derbies, exactly 1:30 after the opening kickoff; however, Galatasaray gave up four straight goals after this and lost the game 4–1.
In July 2009, Galatasaray put Lincoln on suspension due to his absence during pre-season training. He then has been released from the Turkish side. His squad number, 10, was issued to newly appointed captain, Arda Turan.
On 4 February 2010, Lincoln signed a two-year contract with SE Palmeiras. On 8 May 2010, he scored the goal to beat Vitoria 1–0 in opening round of the 2010 Campeonato Brasileiro. He made impressive appearances with Palmeiras in 2010. In 2011, Lincoln was not in the plans of manager Luiz Felipe Scolari, and failed to make usual appearances. He stated that he would like to play more or leave the club.
On 10 August 2011, Avaí announced that Lincoln signed a loan contract with the club from Palmeiras.
