Falter was removed from Wednesday's game against the Diamondbacks with a right groin injury, Matt Gelb of The Athletic reports.
The 25-year-old made a second straight turn through the rotation Wednesday in place of Zack Wheeler (forearm), and the lefty allowed only one run on five hits with six strikeouts and zero walks before the injury forced his exit with one out in the seventh inning. Falter left with a double-digit run lead and is in line for the victory, and it's an unceremonious end to a strong outing. Regardless of his health, Falter may not receive another start with Wheeler possibly reclaiming his rotation spot next week.
