The best rivalry in the NFL, the Steelers against the Ravens, takes place Sunday in Week 4.

“This game is crazy,” Pittsburgh’s Ben Roethlisberger notes. “It’s a special game. I’m still here and (linebacker Terrell) Suggs is still over there. We’ve got a lot of respect for each other in this rivalry. C.J. Mosley, Jimmy Smith, (Brandon) Carr, and (Eric) Weddle now.

“I think we’ve got enough guys here that have played this physical AFC North game. Both there and here, playoff game or whatever it is. I don’t think it will take long if the young guys don’t know now what it’s going to be about.”

Among other things, it’s for first place in the division. Maybe that doesn’t sound significant at this point of the season, but with both teams 2-1, and Cincinnati and Cleveland both winless, the victor at Baltimore takes quick control in the AFC North.

Since the start of 2008, 12 times this game has been decided by three points or fewer.

Suggs, Big Ben’s buddy — well, not exactly — echoes the quarterback’s sentiments.

“You have to get an extra lift in the weight room,” says Suggs, who has more sacks on Roethlisberger (16½) than anyone. “This is, I would say, the biggest rivalry in the NFL. It is definitely the most physical rivalry in the NFL, and it is because of the two teams’ style of play. You don’t cross paths without some things in common. We respect them, but we also know what it is.”

Trevathan suspended

The NFL has suspended Chicago Bears linebacker Danny Trevathan for two games for his frightening hit against Green Bay Packers receiver Davante Adams.

Trevathan has three business days to appeal the suspension.

Adams was taken off the field on a stretcher in the third quarter Thursday night after getting hit in the head during a tackle. Adams tweeted Friday that he was at home and “feeling great.”

Trump urges standing

President Donald Trump on Saturday night stoked the controversy over his call for punitive action against NFL players who take a knee or otherwise protest during the national anthem, tweeting anew that they should remain standing out of respect for the nation and its flag.

Trump tweeted: “Very important that NFL players STAND tomorrow, and always, for the playing of our National Anthem. Respect our Flag and our Country!”

Jaguars to kneel

The Jacksonville Jaguars plan to take a knee before the national anthem is played prior to their game at the New York Jets on Sunday.

Players say in a statement that “every one of us” will “kneel to pray for change, progress and equality for everyone who calls the United States their home.”

The Jaguars (2-1) were criticized locally last week after about a dozen players knelt during the national anthem in London. Jacksonville Mayor Lenny Curry, a Republican, said “it’s stupid” not to stand and honor the American flag.
