Overview

• The Cubs placed Horton on the 15-day injured list retroactive to Sept. 25 because of a right rib fracture, making him unavailable for next week’s Wild Card series against the Padres.
• The earliest postseason eligibility is a potential NLDS Game 5 on Oct. 11, though MLB roster rules and typical recovery timelines make a quick return uncertain.
• Chicago recalled left-hander Jordan Wicks from Triple-A Iowa in a corresponding move.
• With Horton sidelined, Matthew Boyd and Shota Imanaga are lined up for Games 1 and 2, with Jameson Taillon or Colin Rea considered for Game 3 as Craig Counsell adopts a flexible "out-getter" approach.
• Horton has been a major loss given his 11-4 record and 2.67 ERA this season, including a 1.03 ERA in 12 second-half starts.
