Hoerner (oblique) is scheduled to be activated off the 10-day injured list Sunday, Tony Andracki of Marquee Sports Network reports.
The 24-year-old has been sidelined since late July by a strained oblique, but he's poised to rejoin the lineup for Sunday's series finale at Milwaukee. Hoerner should have an everyday role in the middle infield for the final two weeks of the season for Chicago.
