Bryce Harper has been receiving treatment for an injured hip.
Davey Johnson said he wasn't aware of the development. Harper has also dealt with knee issues this season.
"I was a little disturbed that I wasn't informed that he was having some treatment on his hip," Johnson said. "But every time anybody talks to Harp, he says: 'I'm fine, I'm fine, I'm fine.' So I'm going to stick with him."
Harper declined to acknowledge any specific issue, instead reiterating what he has told anyone else who has inquired.
"I'm fine," Harper said. "Just like I told (Johnson). If I was hurting, I'd come out of the game. I feel good."
