Mets’ Jared Young knocked out after taking knee to head in ‘terrifying’ collision

First baseman ran into teammate McLean in sixth inning

Young has concussion symptoms, negative CT scan

Manager says ‘scariest outcomes’ were avoided

New York Mets first baseman Jared Young was carted off the field in the sixth inning of Thursday night’s 3-0 loss to Philadelphia after he was knocked out when struck on the head by a knee of pitcher Nolan McLean as the two converged on Justin Crawford’s slow grounder.

Mets manager Andy Green said a CT scan at a hospital was negative. Young had concussion symptoms and full use of his extremities, according to Green.
