Seigler (trapezius) will start at second base and bat leadoff in Thursday's game versus the White Sox.
Seigler had to be removed from Wednesday's contest with a right trapezius contusion following a play at the plate, but he will not have to miss a start. The 27-year-old has slashed .293/.379/.448 in 18 games for the Red Sox while serving as the team's primary leadoff man of late.
