The Pittsburgh Steelers have scored at least 30 points in a team-record six consecutive games, going 5-1 in that span.

"Our offense is unstoppable," defensive end Cam Heyward said. "To have an offense that can go up and down with anybody, it doesn't matter who's out there — it's pretty special."

The offense helps take pressure off a defense that has had its ups and downs. Pittsburgh (9-5) is fifth in the NFL in rushing defense with 89.4 yards allowed a game but 31st against the pass, giving up an average of 279.1 yards.

The Steelers seemingly should be able to keep putting up big numbers against the injury-ravaged Ravens and woeful Browns in their final two regular-season games.

Antonio Brown has 64 catches for 868 yards in the past six games, leading the league in both categories in that span, while quarterback Ben Roethlisberger has averaged 365.8 yards and thrown 13 touchdown passes.

Owner visits Lions

Detroit Lions owner Martha Firestone Ford chose to spend part of her Christmas holiday with her team.

Ford and about a dozen family members attended part of the Lions' home practice Friday and afterward greeted players on their way off the field.

"Small things like that, it means a lot," guard Larry Warford said.

Defensive tackle Gabe Wright said Ford and other family members exchanged handshakes and hugs with players.

"For her to come out here and support us, especially with the way things are going this year, it really says a lot about her," Wright said.

The Lions (5-9) host the 49ers Sunday.
