GREEN BAY, Wis. – So the Green Bay Packers don't have the NFL's worst rushing defense after all.

They have the Minnesota Vikings to thank for that.

A day after the Packers gave up 189 yards rushing in the season-opening victory over the Chicago Bears, the Vikings got trampled for 230 yards in their loss to the San Francisco 49ers on Monday Night Football.

Through Sunday's games, the Packers were last in run defense among the 28 teams that had played their Week 1 games.

Packers coach Mike McCarthy said the film showed "double-digit missed tackles" even though ProFootballFocus.com charged them with only seven. Not all of the misses, however, were against the run, but his point was well taken.

"That does not cut it," McCarthy said. "We need to do a better job there. It's really the fundamentals of the game are what we spent a bunch of time [on Monday] talking about and emphasizing with our whole football team. That's where we can make our improvement."

The Packers lost one of their best run defenders, inside linebacker Sam Barrington, to an ankle injury in the first quarter. Barrington was on crutches and in a walking boot on Monday, leaving his status in doubt for Sunday's game against the Seattle Seahawks. They also played without safety Morgan Burnett (calf), who often plays near the line of scrimmage, and suspended defensive tackle Letroy Guion, who will miss two more games.

The last time the Packers played without Burnett was Week 8 last season, and the result was much the same. The New Orleans Saints rushed for 193 yards, who dropped the Packers to 32nd (last) in the league in rushing defense.

Now, the Packers have to prepare for the NFL’s best rushing offense from last season. The Seahawks averaged 172.6 yards per game on the ground last year and rushed for 194 yards against the Packers in NFC Championship Game, including 157 from Marshawn Lynch. It was even worse in the Week 1 game last year in Seattle. The Packers gave up 207 yards rushing, although Lynch only had 110 of those.

"I think that everybody in that locker room knows Marshawn Lynch," Packers defensive coordinator Dom Capers said. "They know what he's capable of doing. So, yeah, we'll be looking to make good strides this week in terms of the tackling."
