Razov was drafted by the Los Angeles Galaxy in the third round of the 1996 MLS College Draft. He played two seasons in LA, but did not get much playing time, scoring just one goal, and signed with the expansion Chicago Fire prior to the 1998 season. During his time with the Galaxy, he went on loan with the Sacramento Scorpions of USISL. Razov spent the next seven years with Chicago, save a brief period in 2001 that he spent with Spanish second division club Racing de Ferrol. In his seven years with the Fire he led the club in goals and points five times. He is the club's all-time leader with 76 goals and 190 points. Razov was named to the MLS Best XI in 2003. With Chicago, he won the MLS Cup in 1998 and the US Open Cup in 1998, 2000, and 2003. Following a disappointing 2004 season and clashes with head coachDave Sarachan, Razov was traded to the Columbus Crew in exchange for Tony Sanneh. However, one blemish in Razov's career was being stopped from the penalty spot in the 2003 MLS Cup. The Fire went on to lose the game, 4–2. But Razov did not last long in Columbus. Even though he scored in the 2005 season opener, his tenure with the club lasted five games. Disagreement with head coach Greg Andrulis led to Razov's reuniting with his ex-coach with the Fire, Bob Bradley, at the MetroStars. He was acquired in exchange for John Wolyniec and a partial allocation. After the season, Bradley acquired Razov again, for Thiago Martins and another partial allocation. On April 21, 2007, Razov scored his 100th career regular-season MLS goal. At 33 years old, he became the third player in MLS history to reach 100 goals. At the time, he trailed only Jaime Moreno and Jeff Cunningham, having passed Jason Kreis. All three joined MLS at its inception in 1996.
International
Razov received his first cap with the U.S. national team on March 25, 1995, against Uruguay. Although he never played in the World Cup, he scored a couple of key goals in qualifiers, including one against Guatemala in 2000 and Trinidad and Tobago in 2001. Overall, Razov scored six goals in 25 caps for the US.
