The Tigers will promote Manning from Triple-A Toledo to start Monday against the Marlins in Detroit, Evan Petzold of the Detroit Free Press reports.
Manning is set to rejoin the big club after Kenta Maeda was placed on the 15-day injured list Saturday due to a viral illness. The 26-year-old right-hander holds a 0-1 record over three major-league starts this season and sports a 4.24 ERA and 1.18 WHIP over 17 innings.
