Donaldson is serving as the designated hitter Saturday against the Red Sox.
While it's nothing serious, Donaldson has had some issues with his calf, and the Jays will continue to exercise caution with their star third baseman. Donaldson will be limited to hitting, while Darwin Barney takes his place at third base against Rick Porcello. Donaldson is not likely to return to the field until Tuesday's matchup with the Yankees, per manager John Gibbons.
