Assad was recalled from Triple-A Iowa and will start against the Dodgers on Thursday, Paul Sullivan of the Chicago Tribune reports.
After being optioned down to Triple-A on April 10, Assad will return to the major-league roster less than two weeks later, as Jameson Taillon (groin) lands on the 15-day injured list. Assad has struggled in both the majors and minors this season, so he shouldn't be viewed as a reliable fantasy option.
