The starting quarterback, who injured his right knee during a practice at training camp last month, tossed a 20-yard touchdown pass to Darvin Adams and didn't throw an interception.
He shared the scoring spotlight with rookie backup Chris Streveler, who started the first three games of the season. Streveler ran in a pair of one-yard touchdowns as Winnipeg evened its record at 2-2.
B.C. dropped to 1-2.
Winnipeg middle linebacker Adam Bighill, who played six seasons with B.C. (2011-16), intercepted Lions quarterback Jonathon Jennings twice, taking the second one 54 yards for a touchdown. It was the 10th interception of his seven-year CFL career and his first TD.
Bombers running back Andrew Harris also had a four-yard rushing touchdown in front of 26,567 fans at Investors Group Field, who viewed the game under sweltering conditions. It was 34 C at kickoff, but 44 C with the humidity.
