Watch video of Harper’s collision here.

Washington Nationals right fielder Bryce Harper left Monday’s game against the Dodgers in the fifth inning after hitting an unppaded portion of the right-field wall face-first.

Harper took a semi-circular route in pursuit of a fly ball hit by A.J. Ellis, and didn’t realize he was out of room until he smacked face-first into the scoreboard embedded in the right-field wall. Harper’s hat flew backward as he fell backward, and he remained still on the warning track for some time before Nationals trainers reached him from the first-base dugout.

Harper walked of the field on his own power. Ellis reached third base on the hit, which was ruled a triple.
