Bengals linebacker Vontaze Burfict was ejected Sunday in the second quarter at Tennessee for making contact with an official two plays after a late hit on the Titans’ DeMarco Murray on the sideline.

The linebacker’s ejection left Cincinnati without four defensive starters, with three deactivated before kickoff. Replays showed Burfict pushing aside the left arm of down judge Jeff Bergman on the sideline. Burfict didn’t leave immediately when referee Jeff Triplette announced the penalty, which is an automatic ejection. Burfict didn’t talk to reporters after the game.

“Sometimes what happens is you push back and you touch an official,” Cincinnati coach Marvin Lewis said.

“You can’t do that. He knows better and we pay a price. We pay a price because it hurts us when it’s on the field that way and then he’s not on the field.”

Colts concussion

Jacoby Brissett followed his weekly routine Sunday.

The Indianapolis Colts quarterback kept picking himself up off the turf in Indianapolis 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 finished the game, as he has done every week since replacing Tolzien as the starter in Week 2.

Giants’ troubles

If Ben McAdoo faced questions about his job security as coach of the New York Giants heading into the week, just imagine what it will be like following a loss to the previously winless San Francisco 49ers.

The Giants were thoroughly beaten 31-21 on Sunday.

“We’re not a good team right now,” linebacker Jonathan Casillas said. “Not a good team right now. Hopefully we can go ahead and turn around to be competitive and compete.’’
