Before joining MLS and the Chicago Fire in late in 2004, Herron played two years with Costa Rican Herediano, which he led to Costa Rica's 2004's title, by leading the Costa Rican clausura's tournament with 14 goals and 13 assists. He had joined Herediano after he left Santos de Guápiles in December 2002. Herron had his best season for Chicago in 2006, when the 2006 Budweiser/Fire Golden Boot winner proved his productivity for the "Men in Red" by scoring eight goals in 20 games, with 18 starts. Herron put the team on his shoulders in the team's 2006 Lamar Hunt U.S. Open Cup championship run, scoring four goals and one assist through the competition. His assist and game-winning goal against the Los Angeles Galaxy in the Final at Toyota Park helped the Fire clinch an MLS club-record fourth title to the trophy case.
After two and a half seasons in Chicago, he decided to get back to Club Sport Herediano on a loan from Chicago, but soon after that was sent to Columbus for the second pick in the 2007 MLS SuperDraft (which turned out to be Bakary Soumare) and forward Ryan Coiner. In the MLS Reserve Division he started and played one game for the Crew Reserves, notching one goal in 79 minutes of play.
In February 2008, Herron left Puntarenas and re-signed with Chicago Fire. On November 26, 2008, he was waived by Chicago and he returned to Herediano for the 2009 Verano season. In January 2010 he joined Ramonense and in June 2010 he moved to Guatemala to play for USAC. In summer 2011 he returned to his hometown club after 13 years.
He returned to the United States in January 2012 when he signed with Fort Lauderdale Strikers of the North American Soccer League. In summer 2013 he left Fort Lauderdale to join Atlanta Silverbacks, but left them in August 2013 without any game played for them.
On January 11, 2006, Herron was suspended for six games without pay for his behavior that led to a red card in a 1–0 loss to the New England Revolution during the Eastern Conference Championship game the previous November 6. According to the MLS Soccer Disciplinary Committee, Herron was disciplined for making "unacceptable physical contact" with the referee Terry Vaughn and assistant referee George Gansner, conduct that led to him being sent off in stoppage time. Adding to the severity of his punishment was the fact that Herron returned to the field after the game.
On April 19, 2007, Herron again was involved in a controversial incident during a game against the Revolution. Herron elbowed New England's Jay Heaps early in a nationally-televised game on MLS Primetime Thursday. He did not receive a penalty card, because neither the referee, nor a linesman, saw the action. ESPN commentator Eric Wynalda called the foul, "the worst I've seen in a long time." He was suspended for four games and fined $3,000.  According to Herron, the elbow was in response to Jay Heaps grabbing his "private area" as well as xenophobic and racist comments.
Herron made his debut for Costa Rica in a November 2002 friendly match against Ecuador, also recording his first international goal, and earned a total of 25 caps, scoring 7 goals.
