The Cubs placed Wicks on the 15-day injured list Friday with a right oblique strain, Ryan Herrera of AllCHGO.com reports.
It's the same injury which sidelined Wicks for more than two months before he returned at the beginning of September. He posted a 7.50 ERA and 10:10 K:BB over four starts since his activation, so it's possible the lefty was never fully healthy. Wicks finishes the season having been limited to just 46 innings due to injury, holding a 5.48 ERA and 42:20 K:BB.
