With United, he played in five games before the end of the season. While training following the 2003 season, Martins tore his left ACL. After an extensive rehabilitation process which saw him close to returning to the team, he tore the ACL again. As a result, Martins missed all of United's 2004 season. After the season, Martins was selected 17th overall by Club Deportivo Chivas USA in the 2004 MLS Expansion Draft. He scored the first goal in club history in its second match, a 3–3 draw with San Jose Earthquakes. Martins went on to score two more goals during the season. Martins was traded to MetroStars, with a partial allocation, for Ante Razov in January 2006. He played just one game for the re-branded New York Red Bulls before again being traded, this time to Colorado Rapids, for Peguero Jean Philippe. At the conclusion of the season, he signed with FK Bodø/Glimt of the Adeccoligaen in Norway. Against Tippeligaen side Tromsø IL, he scored two goals in FK Bodø/Glimt's 3–1 away win in the last game before the 2007 campaign. Martins suffered a knee injury in this game and was not 100% when he made his Bodø/Glimt debut in an obligatory match on 9 April 2007, away to Hønefoss BK. Martins contributed greatly for his new club becoming top-scorer as well as scoring in the play-offs. As a result, Martins and FK Bodø/Glimt gained promotion back to the Norwegian Tippeligaen for the 2008 season. Martins had a good year with FK Bodø/Glimt in 2008, and finished fourth even though he was injured for most of the season. However, the success did not last long and Glimt were relegated at the end of the 2009 after a very poor season in Tippeligaen. 2010 started promising for FK Bodø/Glimt in Adeccoligaen, but their initial good form declined, and they ultimately ended up in sixth place. Martins' contract expired at the end of 2010, and FK Bodø/Glimt decided to not offer him a new deal. He subsequently retired from professional soccer. In 2016, Martins was teaching special-needs children and coaching a semi-professional Norwegian soccer team. When not teaching or coaching, he surfs and in October 2016 participated in the Lofoten Masters surfing competition in Unstad in the Lofoten Islands of Norway.
