Overview

• The IL stint is retroactive to Sept. 25, making Horton eligible no earlier than a potential NLDS Game 5 if Chicago advances.
• Chicago recalled left-hander Jordan Wicks in a corresponding move for the season’s final two games.
• Horton’s issue followed an illness with coughing; imaging showed rib concerns, and Jed Hoyer said Saturday’s throwing showed he could not pitch without changing mechanics.
• With Horton sidelined, Matthew Boyd and Shota Imanaga are lined up for the first two Wild Card starts, with Jameson Taillon or Colin Rea in play for a possible Game 3 as Craig Counsell signals flexible pitcher usage.
• Recovery timelines for rib fractures vary, and data cited in reports show pitchers have missed an average of about 88 days, leaving his return timing uncertain as the Cubs host the Padres at Wrigley Field starting Tuesday.
