Bryce Harper is not expected to miss any time after taking a knee to the head against the New York Mets on Monday afternoon.
Harper was running to second base on a ground ball to third by Ian Desmond. He collided with Eric Young, Jr., who was trying to turn a double play, on a hard slide.
He remained down for a couple minutes, before eventually sitting up and then walking off the field escorted by a trainer. He remained in the game for the Washington Nationals.
"[Young] just got me with his knee or his shin and blew me up a little bit," Harper said. "I feel OK now, just got a pretty bad headache and things like that. No haziness or dizziness or anything like that, so that's a plus. But my head hurts pretty bad right now."
Harper said he passed two concussion tests -- one right away before returning to the game, and another one after the game was over.
"I didn't see stars or anything," Harper said. "I've seen stars before. So I knew I was gonna be OK."
