Pereira (concussion) will begin a rehab assignment with Triple-A Charlotte on Saturday, LaMond Pope of the Chicago Tribune reports.
Pereira is in the midst of his second stint of the season on the injured list, this time as the result of a concussion after he previously missed about six weeks due to a right pectoral strain. After being deactivated June 18, Pereira made good progress in his recovery over the All-Star break and has advanced far enough in concussion protocol to test himself in a game setting. Once he's reinstated from the 7-day IL, Pereira will likely fill a short-side platoon role in the Chicago outfield.
