Donaldson (head) is in the lineup for Game 2 of the ALDS Friday against the Rangers, MLB.com's Gregor Chisholm reports.
Donaldson took a knee to his head on a slide into second base in Thursday's Game 1, but he passed concussion tests after the game, and will be able to take the field Friday. As he regularly does, Donaldson will man third base and hit second in the Blue Jays' batting order.
