Amateur career
Dokiwari came out of the same Nigerian amateur boxing program that produced the likes of Peter Konyegwache, David Izon, Richard Igbeneghu, Ike Ibeabuchi, and Friday Ahunanya.
As a boxer Dokiwari was a late comer to the sport. He did not lace a pair of gloves until months after his 18th birthday. Within a span of five years from 1991 through 1996 Dokiwari rose from a virtually unknown in Nigerian boxing circle to become the country's foremost amateur boxing star. Dokiwari won the prestigious Eagle Belt champion of champions title consecutively between 1994 and 1995 in Lagos, Nigeria. Between 1993 through 1996 Duncan was Nigerian super heavyweight champion.
Dokiwari won the gold medal at the 1994 Commonwealth Games in Victoria, Canada. A year later he defeated the Cubans in Cuba by winning the gold medal at the Guama Cup International Boxing Championships. Also in 1995, he was proclaimed the African Boxer of the Year after winning the title at the African Games in Harare, Zimbabwe, where he knocked out all his opponents in the first round.
Gold Medalist at the 1994 Commonwealth Games in Victoria, Australia.
Paea Wolfgramm (Tonga) lost on points, this was a semi-final match, and with the loss Dokiwari won a bronze medal.
Professional career
Dokiwari's boxing career has been plagued with disputes with promoters and managers since turning professional in July 1997. Dokiwari's boxing skill has been honed by reputable trainer such as Eddie Futch, Thell Torrence, and Mike McCallum. Duncan dropped a decision to Fres Oquendo early in his career, and after running off 10 consecutive victories, dropped a unanimous decision to Dominick Guinn. A year after the loss to Guinn, Dokiwari was stunningly TKO'd in the first by unknown Stacy Frazier. Despite the loss, he continued his boxing career recording impressive wins against tough opposition. In December 2006 Dokiwari won the WBC USNBC Heavyweight title with an impressive 4th-round knockout of strong and durable Wllie Palms in Laughlin, Nevada. With the victory Dokiwari became the first man to stop Palms.
Outside the ring Dokiwari was also featured in the motion picture "Undisputed" with Wesley Snipes and Ving Rhames.
