Edwards (back) was activated off the 10-day injured list Friday, Patrick Mooney of The Athletic reports.
Edwards has been sidelined since suffering a back injury in late May, but he's ready to rejoin the Cubs after a four-game rehab stint at Triple-A Iowa. The 27-year-old had six straight scoreless appearances before landing on the IL, but he still has a 5.40 ERA, 1.00 WHIP and 17:8 K:BB this season.
