The Fusion were contracted after the 2001 season along with the Tampa Bay Mutiny, and he was unable to recapture the form that served him well in his first year.

Although he only registered 3 goals and 2 assists in 2004, Chacón's leadership was recognized with a selection to the A-League All-League first team.[3]
