Scott Tolzien

After being cleared through the NFL's concussion protocol late in the third quarter of a 20-17 loss to Pittsburgh, Jacoby Brissett didn't take postgame questions because he was still being evaluated for a head injury by team doctors.

"Scott Tolzien started warming up as soon as Jacoby came out, because we could have lost him for the entire game," coach Chuck Pagano said, explaining one of Sunday's odder scenes. "So he went through the protocol and passed it and got back out there in time to run that series."

Team officials said Brissett was initially evaluated for a concussion on the sideline twice — once with team doctors and once by the unaffiliated neurological consultant. He passed both times. Then, after the game, he developed concussion-like symptoms again and returned to the protocol.
