The NFL strengthened its concussion protocol this offseason and added a third set of eyes at each game to specifically monitor the TV broadcast for signs of concussions. But the new system still seemed to fail Patriots safety Patrick Chung.
An NFL spokesman told the Globe Tuesday, “A joint review by the NFL and NFLPA of the application of the Concussion Protocol regarding New England safety Patrick Chung during the Patriots-Jaguars game is underway.’’
Chung, the Patriots’ strong safety, didn’t play in the second half of Sunday’s 31-20 loss to the Jaguars in Jacksonville, Fla., after he was diagnosed with a concussion at halftime.
