Despite a mild ankle sprain,
Harvey originally suffered the injury in spring training and had the ankle re-evaluated by a doctor on Wednesday.
Harvey worked out Thursday with the ankle taped up.
"A little tape is not going to keep him from pitching the way he can pitch," Mets manager Terry Collins said.
"He's fine. It's nothing," Collins told reporters, per ESPN.
Harvey, who is coming off major elbow surgery, has won all three of his first starts. He owns a 3.50 ERA, a 1.00 WHIP and a 24:1 K:BB ratio over 18 innings. He allowed one earned run over eight innings of work in his previous meeting against the Yankees in 2013.
However, as Harvey makes his return from Tommy John surgery in 2015, the slider has been his least-used pitch through three starts. He has thrown it just 4.3 percent of the time, as he is relying more on his curveball and changeup as secondary offerings.
Sliders are known to put the most torque on a pitcher's elbow, per NJ.com. However, coach Dan Warthen said before Harvey made his third start Sunday against the Marlins that there is no hesitation by Harvey to throw the pitch coming off major elbow surgery.
"No. His curveball has been great, changeup's been great, fastball has been outstanding. It's just not taking place," Warthen said. "We haven't thrown it a whole bunch so it's not exactly where you want it to be yet, but it's still a very useable pitch."
"It was a battle," Harvey said. "I think I kind of ran out of gas."
Harvey did not walk a batter in the game and has walked just one batter in 18 innings this season.
Harvey has been ill of late but said he doesn't want to miss a start.
"I can't swallow anything. Just felt weak, rundown," he said.
Harvey's won all three of his starts in 2015.
Harvey will look to stay perfect Saturday in New York against the Yankees.
Harvey was a bit erratic in his start, allowing a home run to Chase Utley in the first inning, but recording five strikeouts in the first two. Harvey then allowed a run in both the third and fourth innings before settling down and finishing off his start.
Harvey now boasts a 2.25 ERA and will look for his third consecutive win of the year Monday
