Mets first baseman Lucas Duda, who hyperextended his left elbow during Wednesday night's game has been sent for tests and is unavailable for Thursday night's game, manager Terry Collins said.
Duda exited Wednesday's game after a first base collision with Cesar Hernandez in the fifth inning.
Hernandez ran into Duda's arm as the first baseman reached for an errant throw by Robert Gsellman after he fielded a slow ground ball off the mound.
Duda was 0-for-1 with a strikeout before leaving the game. He is hitting .238 with four home runs and seven RBI this season.
Wilmer Flores replaced Duda in the bottom half of the inning as a pinch hitter. Flores, who has an infection, is also unavailable on Thursday night.
