INDIANAPOLIS — Jacoby Brissett followed his weekly routine Sunday.

The Indianapolis Colts quarterback kept picking himself up off the turf and lining up behind center. Perhaps he should have sat out this one.

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

“Scotty (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.

Brissett wound up 14 of 24 for 222 yards with two TD passes and one interception, which came on the first pass he threw after being allowed to return.

SAINTS: Coach Sean Payton said “all the signs are positive” in updating the status of backup running back Daniel Lasco, who had feelings in his extremities after sustaining a spine injury while tackling Brandon Tate of the Bills on a kickoff return.

Lasco was loaded into an ambulance and transported to a Buffalo-area hospital. The Saints were awaiting the results of a final test before learning whether Lasco could join them on their flight home.
