NEW YORK >> The NFL will review how the Panthers’ medical team handled a hit to Cam Newton’s head during Carolina’s loss to Denver in the season opener.

The league said Sunday that it wants to ensure the concussion protocol is being “uniformly applied across all 32 teams.” So along with the players’ association, the NFL will review “the relevant documents and video and interview the involved parties.”

Newton took several hard hits in Thursday night’s game, including one after which he appeared woozy. The union has questioned why Newton didn’t undergo a cognitive exam on the sideline during the game.

NFL spokesman Brian McCarthy reiterated in his statement Sunday that this review “does not mean that we have seen any evidence that the protocol was applied improperly, but simply reflects our obligation to ensure the health and safety of our players.”
