It’s the run defense one game, the pass defense the next and the running game almost every week that is holding the Oakland Raiders back.

The problems keep mounting almost as fast as the point total for the opposition.

A week after being gashed on the ground by Doug Martin and the Tampa Bay Buccaneers, the Raiders were taken apart through the air by Joe Flacco and the Baltimore Ravens in a 55-20 loss Sunday that matched a franchise worst for points allowed in a game.

“That outcome was unacceptable,” coach Dennis Allen said Monday. “We have to be better than that.”

After overhauling the defensive system in the offseason and bringing in the team’s first defensive-minded coach in decades, the Raiders (3-6) are on pace to allow the most points in franchise history. They have allowed at least 40 points in back-to-back games for the first time in a half-century, and the 97 points in the past two weeks are the second-most in a two-game span in team history.

Up next: a visit Sunday from the surging New Orleans Saints.

“I wish there was a magical answer,” Allen said. “I know everybody wants a magical, ‘This is the solution,’ but at the end of the day, and I’ve said this over and over, it’s about us doing our job the right way every single time.”

Chiefs

DORSEY PLACED ON INJURED RESERVE: Kansas City placed defensive end Glenn Dorsey on injured reserve with a calf injury and added defensive back Neiko Thorpe to the 53-man roster.

Dorsey, the former LSU and East Ascension High star, played just four games this season. He injured his left calf in practice in September and missed four games, then injured his right calf during a 31-13 loss to the Chargers on Nov. 1. The former first-round pick finishes the season with seven tackles and no sacks.

Eagles

‘SIGNIFICANT’ CONCUSSION FOR VICK:Philadelphia coach Andy Reid said Michael Vick suffered a “pretty significant” concussion and told the quarterback to stay home Monday and rest.

Reid said he could not immediately rule out Vick for Sunday’s game at Washington. Reid, though, made it sound likely that rookie Nick Foles will get the start.

Foles will take the first-team snaps when the Eagles return to practice Wednesday. Foles was 22 of 32 for 219 yards with a touchdown and an interception after taking over for Vick in the second quarter of Philadelphia’s loss to Dallas on Sunday.

Reid said Vick complained of a headache and fatigue Monday. Foles would be making his first career start.

49ers

SMITH HAD BLURRED VISION: San Francisco quarterback Alex Smith threw a 14-yard touchdown pass in the second quarter of Sunday’s 24-24 tie against the St. Louis Rams while playing with blurred vision before coming out with a concussion.

Coach Jim Harbaugh said Smith connected with Michael Crabtree six plays after he began experiencing blurred vision on a 1-yard keeper early in the second quarter. He had taken a vicious hit from linebacker Jo-Lonn Dunbar.

Harbaugh said Smith improved overnight and would see a neurologist later Monday.

His status is unclear for next Monday night’s game against the Bears.

Bills

JACKSON OUT WITH CONCUSSION: Buffalo running back FredJackson was diagnosed with a concussion and was ruled out from playing against Miami on Thursday.

Jackson was hurt in the final minute of Sunday’s 37-31 loss at New England after taking a blow to the head while being tackled by linebacker BrandonSpikes.
