The Chicago Cubs have clinched a postseason berth for the first time since 2020 this season, but to start their playoff run, they'll be without starting right-handed pitcher Cade Horton.

Horton was placed on the 15-day injured list retroactive to Sept. 25, set to miss at least the wild-card round with an untimely rib fracture, ESPN's Jesse Rogers reported on Saturday. The soonest he would be eligible to return would be for Game 5 of the divisional round, if the team were to advance beyond the wild-card series.

The team has recalled lefty Jordan Wicks from Triple-A Iowa in a corresponding move, the team announced.

Horton has been considered a frontrunner to win NL Rookie of the Year thanks to his strong performance since the All-Star break. In the second half of the season, Horton has a 1.03 ERA over 61.11 innings pitched in 12 starts. The righty holds an 8-1 record, with a 54:15 K:BB ratio in that span.

Wicks has a 3-4 record in the minors this year, with a 3.80 ERA over 71 innings pitched. He's pitched 11.1 innings in relief for the Cubs this year, with a 7.94 ERA as a reliever.
