Overview

• Cubs manager Craig Counsell said Friday that Horton will not be active for the Division Series as he recovers from a right rib fracture.
• Horton remains on the 15‑day injured list retroactive to Sept. 25 after leaving his Sept. 23 start with back tightness following an illness.
• Team officials say Horton has only been playing catch on flat ground, and he is not expected to be ready even if the series reaches a Game 5 despite being technically eligible.
• Chicago named left‑hander Matthew Boyd its Game 1 starter on Saturday, while Milwaukee will start All‑Star Freddy Peralta.
• Despite a standout rookie season (11–4, 2.67 ERA in 23 appearances), Horton’s absence shifts more innings to veterans as the Cubs map out their postseason rotation.
