FILE - In this Dec. 8, 2011, file photo, Cleveland Browns guard Jason Pinkston (62) and wide receiver Greg Little (15) check on quarterback Colt McCoy (12) after he was hit by Pittsburgh Steelers outside linebacker James Harrison in the fourth quarter of an NFL football game in Pittsburgh. McCoy injured his hand and was wobbled by a hit from linebacker and renowned Browns blaster James Harrison. The NFL has denied James Harrison's appeal of a one-game suspension for a helmet-to-helmet hit on Cleveland quarterback Colt McCoy, and the Pittsburgh Steelers linebacker will sit out the game scheduled for Monday, Dec. 19, against the San Francisco 49ers.

BEREA, Ohio — The NFL will require teams to place certified athletic trainers in the press box to help monitor head injuries, a result of the Browns' failure to test quarterback Colt McCoy for a concussion.

NFL spokesman Greg Aiello confirms that the league will send a memo to all 32 clubs Tuesday or Wednesday to explain the new protocol. The trainer will be able to monitor the entire game without distraction to inform medical staff on the field of any potential head injuries.

The new rule was first reported by Charley Casserly of CBS.

McCoy sustained a concussion Dec. 8 against Pittsburgh. Although laid out on an illegal hit by Steelers linebacker James Harrison, the QB was not tested for a concussion and the Browns sent him back in the game after two plays.

The league and union met with the team last week to discuss its handling of the injury. Team president Mike Holmgren said McCoy did not display symptoms of a concussion on the field and the team's medical staff did not test him because they did not see Harrison's vicious hit.
