Donaldson will not be in Saturday's lineup against Texas, Arden Zwelling of Sportsnet.ca reports Friday.
Donaldson missed 39 games with a calf injury before making his return Friday night, in which he went 1-for-4 with two strikeouts. The Blue Jays have expressed a desire to take care with their star third baseman, so expect semi-regular rest days for him in his first week or two back on the roster.
