Manager John Gibbons thinks that Donaldson (calf) has a good chance of returning to the lineup Friday and that Donaldson "is feeling better today," Ben Nicholson-Smith of Sportsnet reports.
Donaldson left Wednesday's game against the Rays in the seventh inning due to the ailment, although between the team's off day Thursday and how much the team downplayed the issue, a Friday return for the third baseman is seeming to be more realistic as game-time approaches. Of course, how he's feeling on the day of the game is most important and a start isn't set in stone until the lineup is released, but this development is definitely an encouraging sign for the Blue Jays and Donaldson's fantasy owners.
