Donaldson has been scratched from the Blue Jays' lineup Thursday with left knee soreness, Arden Zwelling of Sportsnet.ca reports.
The last-minute change deprives the Jays of their No. 3 hitter. Kendrys Morales will give up his day off and instead hit third Thursday. As for Donaldson, the club should provide more details in the near future, but considering his lower-body issues this year, this deserves at least a close look.
