The 20-year-old left-hander left his start with double-A New Hampshire with left biceps discomfort in the fourth inning of a game last Thursday.
Tiedemann is 0-1 with a 4.97 ERA, 23 strikeouts and seven walks in four starts this year with New Hampshire.
Meanwhile, reliever Adam Cimber (rhomboid) threw a bullpen Tuesday and reported feeling “pretty good,” manager John Schneider said.
The Blue Jays hope he makes a rehab appearance with class-A Dunedin in the next few days.
Fellow right-hander Mitch White (shoulder) is scheduled to make another rehab appearance on Friday or Saturday with triple-A Buffalo.
White, who hasn’t pitched in the majors this year, threw 67 pitches over four innings with Buffalo on Sunday.
