D'Arnaud left Saturday's game in the seventh inning after being hit by a pitch in his second at-bat, Matt Ehalt of The Record reports.
The team has yet to announce whether d'Arnaud was removed for precautionary reasons or whether he did suffer an injury after being hit on the arm by a Zach McAllister offering. Regardless, d'Arnaud is done for the day and has been replaced behind the plate by Kevin Plawecki. The Mets will likely release an update on d'Arnaud's status following Saturday's contest.
