Blue Jays manager John Schneider told reporters on Monday that Scherzer’s rehab assignment will continue on Wednesday, when the three-time Cy Young winner starts for the triple-A Bisons.
Buffalo is at home this week for a six-game set with the Scranton/Wilkes-Barre RailRiders — an affiliate of the New York Yankees.
Scherzer last pitched on Friday with the high-A Vancouver Canadians, throwing 49 pitches (33 strikes) across three innings. He allowed three hits and two earned runs, striking out three batters and walking a pair.
The 41-year-old last pitched for Toronto on June 10 against the Philadelphia Phillies before hitting the injured list later that week with back spasms.
Various ailments have limited Scherzer to just six starts and 22 innings with the Blue Jays this season, in which he owns a 10.23 ERA, 14 strikeouts and 11 walks.
He was also sidelined from April 24 to June 10 due to right forearm tendinitis and left ankle inflammation.
