Mets outfielder Johneshwy Fargas left Monday's game against the Colorado Rockies prior to the fifth inning after crashing hard into the center field wall.
Veteran Cameron Maybin moved from RF to CF, and rookie Khalil Lee came in to the game to play RF.
Fargas suffered a left AC joint sprain, according to the team.
He's the fourth CF to go down this month, joining Brandon Nimmo, Kevin Pillar, and Albert Almora Jr.
In seven career games, Fargas is batting .286 with three doubles, a triple, and 3 RBI.
