context_page_description: Dariusz Michalczewski is a Polish-German former professional boxer who competed from 1991 to 2005. He held multiple world championships in two weight classes, including the WBA, IBF, WBO and lineal light-heavyweight titles between 1994 and 2003, and the WBO junior-heavyweight title from 1994 to 1995.
context_section_description: Michalczewski had a perfect record of 48-0 when he faced Julio César González of Mexico in defense of his title on 18 October 2003. Coming into the fight, he was within one victory of tying Rocky Marciano's record of 49 wins with no losses. A win also would have put him just one victory short of Joe Louis' all-time record for successful defenses at any weight class. However, as when Larry Holmes went for the same record against Michael Spinks, the now 35-year-old Michalczewski was unable to pull it off. He lost a controversial split decision to the 27-year-old Gonzalez at the Color Line Arena in Hamburg, and his career record dropped to 48-1.
  Despite the loss, he still holds the record for the most consecutive successful world title defenses at light-heavyweight.
