Bryce Harper is headed back to Washington, D.C. to undergo tests on his hip.
Harper aggravated the lingering issue during batting practice before Saturday's game.
"He's going to go to see the doctor [Sunday], figure out what it is, treat it, and he'll meet us in New York, hopefully," Davey Johnson said.
Harper is hitting .273/.377/.504 with 19 home runs and 49 RBIs this season.
