After feeling pain in the foot, Green was examined by a doctor. He was told to put a boot on the foot and walk with crutches for at least the next several days, to see how the foot reacts.
"The doctor said it's not in a bad place, hopefully," Green said. "He didn't think it was something where I could injure it worse by playing. I just know it's hard to run. And it hurts when I try to stand on my toes."
Green pulled his pants leg up to show significant swelling on top of the right foot. Still, he was able to slide the foot into his dress shoe.
He injured the foot fouling off a ball against the Marlins' Sergio Mitre. He stayed in the game and was one of five Mets to score in the ninth.
The Mets, who play the Marlins for the next two days and then have Monday off, figure to use Carlos Gomez in Green's spot short-term. Green is hitting .314 for the season.
