A tough season for CeeDee Lamb appears to have just gotten even worse.

The Dallas Cowboys wide receiver Lamb suffered an apparent concussion on a frightening play during his team’s “Thursday Night Football” game against the Detroit Lions. In the third quarter at Ford Field in Detroit, Michigan, Lamb dove for a ball in the end zone but could not come down with it.

On his descent, Lamb hit the back of his head on the turf. As a result, his hands immediately went into the “posturing position,” which is a tell-tale sign of a concussion.

Here is the video.
