Peña and the Astros hoped it was a day-to-day injury, but additional imaging revealed the fracture. Mauricio Dubón started at shortstop Saturday and Sunday and will likely continue to be the starter during Peña's absence. Since 2021, the average missed time for a rib fracture has been 33 days, per the Baseball Prospectus Recovery Dashboard.

Houston Astros shortstop Jeremy Peña has a fractured rib and will be placed on the 10-day injured list. The team says Peña has a small fracture in his left rib cage.

Shortstop Jeremy Pena was placed on the injured list Monday by the Houston Astros. Chicago Cubs starter Cade Horton hit Pena by a pitch in the ribs on Friday and Pena missed both Saturday's and Sunday's games. He was still feeling the injury and subsequent medical examainations revealed a fractured rib.
