Zbigniew "Bishop" Dolegiewicz (July 8, 1953 – October 29, 2008) was a Canadian professional track and field athlete and coach who specialized in the shot put and the discus throw.

He won a second Pan American medal in 1979 and began competing in the World's Strongest Man competition, highlighted by a fourth-place finish in 1980.

He sold the drug to Charlie Francis in 1981, who acquired it for his trainee Ben Johnson (the athlete whose failed test sparked the inquiry).

Originally from Toronto, he began studying at the University of Texas in 1972 and ranked sixth in the shot put at the NCAA Men's Outdoor Track and Field Championship the next year.

[10] Dolegiewicz regained his national shot put title in 1979 with a championship record throw of 20.23 m and finished ahead of Pauletto to take the silver medal at the 1979 Pan American Games.

[11] On the athletics circuit that year he won a silver at the 1981 Pacific Conference Games,[12] as well as another national title and fifth place at the 1981 IAAF World Cup.

In mid-1981 he sold 500 tablets of Dianabol to track coach Charlie Francis, marking the beginning of sprinter Ben Johnson's drug use.

[14] Dolegiewicz also saw the opportunity to sell Dianabol at the international competition, and he brought along several hundred tablets of the drug on the trip to Helsinki.

[8] Around this period he married a fellow throws athlete, Gale Zaphiropoulos who competed internationally for the United States, but the two later were divorced.
