Gregorius left Tuesday's game against the Blue Jays after getting hit in the back of the helmet with a pitch, Todd Zolecki of MLB.com reports.

EDGE Analysis

Gregorius initially remained in the game, which could be a positive sign, but he later left the dugout with a team trainer. If he suffered an injury serious enough to cost him regular-season action, Jean Segura would likely slide back to shortstop, opening up second base for Scott Kingery.
