Sekorski made his professional debut on January 21, 1981, with a four-round decision win against Rick Kellar. He won his first 13 professional matches, losing for the first time to 41-5-2 Marvin Camel on May 21, 1983, in Billings, Montana. Sekorski won three more times before his next loss, to 11-1 Pierre Coetzer in Johannesburg, South Africa. Sekorski continued to fight boxers of a high calibre, his biggest win being a sixth-round TKO of former world champion Leon Spinks in Detroit Lakes, Minnesota on August 2, 1986. Sekorski won the vacant Minnesota State Heavyweight title with a 3rd-round TKO against Percell Davis in August 1988, then lost a fight for the WBC Continental Americas heavyweight title to former WBA heavyweight champion Michael Dokes in December of the same year. Thereafter Sekorski would lose more than he won, concluding his career with a loss to Jimmy Lee Smith on November 22, 1993.
Sekorski also lost a fight by TKO in the 3rd round to the returning George Foreman, not going down despite the hard-hitting Foreman landing several heavy punches.
Sekorski compiled a professional record of 23-11 with 13 wins by knockout during a twelve-year professional career.[1]
