Gausman isn't dealing with an injury and will pitch in a minor-league game Sunday, Ben Nicholson-Smith of Sportsnet.ca reports.
Gausman was originally scheduled to pitch Saturday against the Tigers, but it looks like the Blue Jays simply altered their plans. He could have pitched in a Grapefruit League game against the Yankees on Sunday, but he'll face minor-leaguers instead to give the Yankees' big-league bats fewer reps against him.
