Ben Roethlisberger placed in NFL's concussion protocol

SEATTLE -- Steelers quarterback Ben Roethlisberger has been placed in the NFL's concussion protocol after leaving the field late in the fourth quarter of Sunday's 39-30 loss to the Seahawks.

Roethlisberger self-reported concussion symptoms to the team, which evaluated him shortly thereafter, according to the Steelers.

Roethlisberger was in the locker room after the game but did not address the media.

On the fifth play of a 14-play scoring drive, Roethlisberger took a high-low hit from Seahawks pass-rushers Michael Bennett and Bruce Irvin that resulted in a roughing the passer call.

Roethlisberger was on the ground for a few seconds after the play. He got up with the help of teammates and didn't show noticeable symptoms while standing up. He proceeded to play the next nine plays, leading the Steelers to the red zone for a field goal.

Backup Landry Jones manned the offense on the final drive while Roethlisberger headed to the locker room.

Steelers coach Mike Tomlin said his eyes were on the field and any testing was going on behind him. Tomlin declined to discuss details but added that the Steelers are "going to do what's appropriate and take care of our guys."

Players were uncertain what exactly happened.

"Hopefully he's OK," said wide receiver Markus Wheaton, who finished with a career-high 201 receiving yards.

Linebacker Ryan Shazier also is in the concussion protocol. Tight end Heath Miller left the game in the second quarter with a rib injury.
