Lux was removed from Sunday's Game 1 of the NLCS due to hip flexor tightness, Bill Plunkett of The Orange County Register reports.
Lux talked to a trainer after grounding out in the sixth inning and didn't take the field to start the seventh frame. It's now known he's battling hip flexor soreness, which likely means he'll be tabbed day-to-day. Regardless of his health, the lefty-hitting Lux isn't likely to be in the lineup for Game 2 against southpaw Sean Manaea and the Mets.
