In a scary scene from Thursday Night Football, Carolina Panthers linebacker Luke Kuechly left the game in the fourth quarter with a concussion.。

Kuechly took a hit to the back of the head, near the neck, in addition to twisting his knee awkwardly on the play. Injuries can often be emotional for players, but Kuechly, the league leader in tackles, was a wreck. He sobbed as the medical staff tended to him.

Richard Sherman slammed the NFL in September, calling it a "bottom line business" when it comes to taking care of its players. Recently, MVP Cam Newton — the latest poster child of the concussion debate, thanks to the hits to the helmet he took in Week 1 — called out the league's officials. He said he doesn't feel safe anymore. 。

Kuechly just provided a poignant example of that harsh reality.。

Don't think I've seen a player sob until hyperventilating after hurting knee on a football field the way Luke Kuechly just did. Sad sight.。

The league pledged $100 million to concussion research in September, but its biggest response to the head injury debate this year has been its updated concussion protocol, which now provides additional support for spotting concussions on the field. 。If the NFL had lost sight of the human element of this debate in the midst of all this policy, Kuechly's injury is a disturbing reminder.。If the NFL had lost sight of the human element of this debate in the midst of all this policy, Kuechly's injury is a disturbing reminder.。
