Wilson will be called up from Triple-A Indianapolis to start the second game of Thursday's doubleheader against the Reds, C. Trent Rosecrans of The Athletic reports.
Wilson was sent down by Pittsburgh on Sunday but will rejoin the major-league club to make a spot start during Thursday's nightcap. He's had lackluster results over his last five major-league outings and has posted a 10.89 ERA and 2.27 WHIP in 20.2 innings during that time.
