Carrasco allowed three runs in two innings against the Braves, and his outing was interrupted by a 55-minute rain delay in the second inning. He returned after it to get the final out of the inning, but he winced on his last pitch and was pulled with left side tightness.
"It just got tight a little bit [on the last pitch], and I don't want to push any more," he told reporters after the game.
"We just got to wait to see how I feel tomorrow, and then we'll go from there."
Mets manager Buck Showalter said Carrasco threw an inning in the batting cage during the rain delay, so kept loose during the down time.
"He was good," Showalter said when asked if he second-guessed himself bringing back Carrasco after the rain delay. "Just that one pitch got him."
Any time missed by Carrasco (13-5, 3.92 ERA) would be significant for the NL East-leading Mets. The right-hander had gone 5-0 with a 1.69 ERA over his last seven starts, and New York was 7-0 over that stretch entering Monday's series opener.
