Ravens at Vikings: John Harbaugh says it's not all on Joe Flacco to figure things out

Sunday:  Noon at U.S. Bank Stadium (Ch. 4, 100.3-FM, 1130-AM)

• Ravens (3-3) lost at home to the Bears in overtime 27-24 for Baltimore's third loss in the past four games.

• A 77-yard punt return for a touchdown by Ravens receiver Michael Campanaro, right, helped Baltimore rally from a 17-3 deficit to force overtime against Chicago.

• Baltimore gives and takes away the football, totaling 14 takeaways on defense (nine interceptions, five fumbles) and 12 giveaways on offense (eight interceptions, four fumbles).

• Quarterback Joe Flacco has struggled this season, averaging only 167.2 yards per game and throwing four touchdowns to eight interceptions.

• At 35 years old, outside linebacker Terrell Suggs leads the Ravens with 4.5 sacks through six games. He's second among active NFL players with 119 career sacks, trailing only Carolina's Julius Peppers (150). Suggs is 21st on the career list.

• Sunday's game will be a rarity featuring two of the NFL's most tenured defensive players in Suggs and Vikings cornerback Terence Newman. Since both entered the league in 2003, Newman and Suggs rank second and fifth among NFL defenders with 200 and 187 starts, respectively.

• Ravens coach John Harbaugh on Suggs: "He's one of those rare guys walking around this planet, so start with that. I think he's worked harder than he ever has in this later part of his career."

• Harbaugh is in his 10th season as Ravens head coach with an 88-62 record in the regular season and 10-5 playoff record, with one Super Bowl championship in 2012.

• Harbaugh is only the third head coach in the history of the Ravens, a franchise that began in 1996 with Ted Marchibroda calling the shots. Former Vikings offensive coordinator Brian Billick, who coached the Ravens from 1999 to 2007, led Baltimore to its first Super Bowl title in 2000.

• On Flacco's struggles: "We just have to figure it out as a group. It's a collective effort, from game planning to the precision and execution. It's on everybody. The quarterback definitely shoulders the criticism, but it's a group effort."

• On former Vikings WR Mike Wallace, who leads the Ravens with 239 receiving yards: "He's a big-play threat. He's made those plays for us.
