BALTIMORE — The Baltimore Ravens are angry and calling for a review of the rule book after watching quarterback Joe Flacco being helped off the field, bleeding and disoriented following a late hit.

Flacco sustained a concussion Thursday night against Miami after he went into a slide designed to prevent being tackled. The Ravens were off Friday, and provided no update on the quarterback’s condition.

It is unclear if Flacco will be ready when Baltimore plays on Nov. 5 at Tennessee.

Dolphins linebacker Kiko Alonso crushed Flacco late in the first half Thursday, forcing his exit in a game the Ravens would win 40-0. Alonso received a penalty for unnecessary roughness, but that was of little consolation to the Ravens.

“He was sliding, and the guy came in high. They’re trying to take that play out, but it happens,” Baltimore safety Eric Weddle said. “Maybe they’ll look at in in the offseason, and in that situation, the guy should get ejected.”

Flacco threw a touchdown pass earlier in the game and helped Baltimore take a 13-0 lead before Alonso’s hit ripped the helmet from the quarterback’s head and put a gash near his ear that required stitches.

Alonso insisted the hit to the head was unintentional.

“I thought he was going to slide. And then, I had to hit him, because he slid too late,” Alonso said. “It was bang-bang. I don’t know what else I could have done.”

If Flacco can’t go, the Ravens will turn to backup Ryan Mallett, who threw a touchdown pass three plays after Flacco left.

DOLPHINS: Injured Quarterback Jay Cutler will start Nov. 5 against Oakland despite what Coach Adam Gase called “multiple cracked ribs” suffered when hit by New York Jets linebacker Jordan Jenkins on Sunday.

Cutler didn’t play Thursday.

TEXANS: Chairman and chief executive Bob McNair apologized after a report said he declared “we can’t have the inmates running the prison” during a meeting of NFL owners over what to do about players who kneel in protest during the national anthem.

McNair said he regretted using the expression and that he was not referring to players.

“I used a figure of speech that was never intended to be taken literally,” McNair said. “I would never characterize our players or our league that way and I apologize to anyone who was offended by it.”

Texans left tackle Duane Brown said he was “sickened” by McNair’s words

BILLS-JAGUARS: Jacksonville traded for Buffalo nose tackle Marcell Dareus, beefing up the middle part of one of the NFL’s best defenses.

The Jaguars sent a sixth-round pick in the 2018 draft to the Bills in exchange for the 330-pound run-stopper.

Jacksonville ranks sixth in total defense and second in passing defense, but 31st against the run. Dareus, a two-time Pro Bowl selection and the third overall pick in the 2011 draft, should help bolster the middle of Jacksonville’s line.

VIKINGS: Case Keenum will make his sixth start in eight games at quarterback Sunday when Minnesota plays Cleveland in London.

Coach Mike Zimmer confirmed the decision that he’d been coy about all week regarding Keenum, who has played well in relief of Sam Bradford.

Zimmer called the muddled quarterback situation “a good problem to have.”

DISCIPLINE: Jets linebacker Darron Lee was fined $36,464 by the NFL for a roughing the passer penalty and another $9,115 for a facemask call in New York’s loss at Miami last Sunday.

Lee, in his second season, has been fined four times this year for a total of $72,925.

Jets wide receiver Robby Anderson was also fined $12,154 for tossing his helmet in frustration toward the end of the 31-28 loss.

Also from that game, Miami defensive lineman Ndamukong Suh was fined $9,115 for a facemask penalty.

Cincinnati linebacker Vontaze Burfict added to his lengthy list of infractions, receiving a fine of $12,154 for kicking at the head of Pittsburgh fullback Roosevelt Nix.
