Another fine day for Lynch

Marshawn Lynch’s return to the NFL came with a price.

The Oakland Raiders running back was fined $12,154 by the league for flipping the middle finger on both hands last Sunday in the fourth quarter of the team’s 26-16 victory at Tennessee. Lynch, who was retired last season, ran for 76 yards on 18 carries and caught a 16-yard pass. Three Pittsburgh Steelers — linebacker Ryan Shazier, cornerback William Gay and safety J.J. Wilcox — were each fined $24,309 for unnecessary roughness against Cleveland.

New Orleans Saints safety Kenny Vaccaro and linebacker Alex Anzalone were also docked $24,309 for hits to the head, as was the Los Angeles Chargers’ Melvin Ingram.

Fined $9,115 yesterday were San Francisco’s Jaquiski Tartt, the New York Jets’ Darron Lee, Detroit’s Jarrad Davis and Green Bay’s Martellus Bennett — all for unnecessary roughness — and Minnesota’s Linval Joseph (facemask).

Sherman iffy

Seattle Seahawks cornerback Richard Sherman is listed as questionable for tomorrow’s game against the 49ers with a hamstring strain.

Seattle coach Pete Carroll said Sherman would be a gametime decision, but he sounded optimistic the veteran corner would be able to play.

Officially, Sherman was limited in practice yesterday. He has started 91 straight games for Seattle dating back to the middle of the 2011 season, rarely even coming close to missing a game with an injury.

Bradford set to go

Minnesota Vikings quarterback Sam Bradford is expected to play at Pittsburgh despite a knee injury that limited him all week in practice.

Coach Mike Zimmer said he anticipates Bradford will play tomorrow. Bradford was listed as questionable on the injury report.

Bradford was named the NFC Offensive Player of the Week for his performance Monday in the opener against New Orleans. He showed no signs of trouble during the game . . . .

The Oakland Raiders signed offensive lineman Donald Penn to a $21 million, two-year extension, ensuring the Pro Bowl left tackle will remain with the team through the 2019 season . . . .

Miami Dolphins linebacker Rey Maualuga has been ruled out of tomorrow’s season opener at the Chargers because of a hamstring injury.

Receiver Jarvis Landry was listed as questionable because of a knee injury and was limited in practice. Coach Adam Gase said Landry has some swelling but likely will play.

Bengals fire OC

The Cincinnati Bengals made the first step toward digging out from their historically bad start, replacing offensive coordinator Ken Zampese a day after they again failed to get into the end zone.

Quarterbacks coach Bill Lazor will take over as coordinator.
