PITTSBURGH — Ben Roethlisberger’s right arm is in a cast while he recovers from right elbow surgery.

Joe Flacco is trying to keep the Denver Broncos afloat. Terrell Suggs is in Arizona.

Time to see if the professional hatred that’s long been a hallmark of one of the AFC’s most bitter rivalries can be handed down from one generation to the next.

Lamar Jackson saw a taste of it last season as a rookie, playing in a handful of series when the Ravens came into Heinz Field and won last September.

“They play that little song, and they wave their little flags and stuff, with the little towels around,” Jackson said. “It was pretty dope. I enjoyed it. I did, I really did.”

Maybe, but his vantage point will be considerably different on Sunday when the second-year quarterback leads Baltimore (2-2) into Pittsburgh (1-3) in a game that features new faces but similar stakes.

“It’s going to be pretty crazy,” Jackson said. “No Ben, a whole new team, a new era. We just have to get ready for it.”

The Steelers looked ready to compete by crushing the hapless Bengals on Monday night. Mason Rudolph threw for 229 yards and two scores.

The Ravens, however, represent a significant step up in quality.
