In a scary scene at Citi Field, Mets first baseman Jared Young was forced from Thursday’s game against the Phillies with an apparent head injury in the top of the sixth inning after Nolan McLean crashed into him.

The play occurred when Philadelphia’s Justin Crawford hit a slow chopper down the first base line, where Young first looked ready to field the ball, but went back toward the bag as McLean also approached the ball.

With both players off balance, McLean’s knee ended up hitting Young’s head and Young immediately went to the ground and stayed there for several minutes as trainers quickly came to his assistance.

Members of both teams were stunned as Young was removed from the field on a cart.

Young gave a thumbs up as the cart was leaving the field and received an ovation from the Citi Field crowd.

McLean, who appeared shaken by the play, stayed in the game after talking with interim manager Andy Green with the Mets trailing, 1-0 and runners on first and third following the two-out infield single.

McLean finished the inning by striking out Garrett Stubbs, while Young was replaced at first by Mark Vientos.
