Seager was scratched from the Rangers' lineup ahead of Thursday's game against the Dodgers for undisclosed reasons, Kennedi Landry of MLB.com reports.
Seager returned to the lineup Wednesday after missing four games with a hamstring issue, and it's possible he aggravated that injury while going 1-for-3 with a three-run homer and a walk. Travis Jankowski will step in as Texas' designated hitter, with Josh Smith starting at shortstop.
