Brown (oblique) will be activated from Triple-A Iowa's 7-day injured list and will pitch Sunday versus Toledo, Andy Martinez of Marquee Sports Network reports.
The 23-year-old hasn't seen game action since late July, when he suffered an oblique injury. Brown has a 4.72 ERA in 14 starts for Iowa this season, but he gave up just three runs with a 16:6 K:BB in his three starts prior to landing on the injured list.
