When Chip Kelly announced Eagles starting safety Malcolm Jenkins wouldn't be practicing on Wednesday due to a concussion, questions were raised. When did Jenkins suffer this concussion? He didn't leave the Eagles-Cowboys game at any point. He played 100% of Philadelphia's snaps, along with six special teams snaps. Jenkins spoke with the media on Thursday and admitted that he originally hid his concussion from the Eagles.

That's not good. It's understandable that Jenkins didn't want to hurt his team by leaving the game, but concussions just can't be ignored like this. Here's the play where the injury occurred:

One can wonder if Jenkins' condition caused him to struggle with covering Cowboys slot receiver Cole Beasley.

The NFL employs independent concussion specialists on the sideline who are supposed to examine players who show concussion symptoms. The NFL also empowers concussion spotters who watch from the press box and have the power to stop the game and force a player to be examined on the sideline. Obviously this system failed on Sunday night during the Eagles-Cowboys game.

The good news for Jenkins is that he's been cleared by an independent neurologist to return to practice. He will likely start at safety for the Eagles on Sunday against the Dolphins.
