The Rangers placed Seager on the 7-day concussion injured list Monday, Evan Grant of The Dallas Morning News reports.
Seager was involved in a collision at home plate with the Royals' Carter Jensen last Thursday, resulting in an injury to his ribs and jaw in addition to a mild concussion. Ezequiel Duran will likely handle the bulk of the reps at shortstop while Seager is sidelined, though Josh Smith (illness) could also be in the mix after he returned from the IL on Monday.
