Lauer will start Sunday against the White Sox instead of Saturday as previously scheduled due to an illness, Keegan Matheson of MLB.com reports.
An ailment has apparently been working its way through the Blue Jays' clubhouse, and it will push Lauer back one day in the rotation. The left-hander made his season debut last Sunday versus the Athletics and had a strong showing, striking out nine while giving up two runs on three hits and a walk over 5.1 innings.
