Overview
- Kyle Karros suffered a head injury after colliding with shortstop Ezequiel Tovar while chasing a ground ball at Chase Field, and the team moved him to the seven-day concussion injured list for evaluation.
- The placement on the concussion list triggers MLB's concussion protocol and removes the Rockies' regular third baseman from the lineup while he is monitored.
- Infielder Adael Amador was recalled from Triple‑A Albuquerque to fill the roster spot; he has strong Triple‑A numbers this year but has struggled in limited major league plate appearances.
- Right‑handed reliever Jeff Criswell was activated from the 15-day injured list and optioned to Triple‑A after rejoining the club this season following Tommy John surgery.
- Karros has been a breakout regular this season with solid offensive totals, the Rockies' 40-man roster now sits at 38, and the club has short-term roster flexibility to make additional moves if needed.
