Prukop has also been a member of the Toronto Argonauts, Calgary Stampeders, Winnipeg Blue Bombers, New Jersey Generals, and BC Lions.

[2] After struggling in the Ducks' fifth game against Washington State, Prukop was benched and freshman quarterback Justin Herbert took over for the rest of the year.

Following the Ray's retirement, Prukop became the team's third-string quarterback entering the 2019 Toronto Argonauts season, but was soon elevated to back up following an injury to starter, James Franklin.

He saw his first action at quarterback on July 25, 2019, against the Edmonton Eskimos in relief of McLeod Bethel-Thompson, but he threw two interceptions and the team lost 26–0.

[5] Later that season, after the Argonauts had been eliminated from post-season contention, he again saw game action and threw his first career touchdown pass to Rodney Smith on a 13-yard completion on October 26, 2019, against the Ottawa Redblacks.

[15] Primarily rostered as the 3rd string QB and short yardage pivot, he dressed for 12 regular season games where he completed seven of 14 pass attempts for 181 yards and two touchdowns.

Prukop also played in the 109th Grey Cup game where he had five carries for nine yards and two touchdowns as the short yardage QB, but also had two pass attempts with no completions and one interception in the loss to the Toronto Argonauts.
