Safety Kam Chancellor helped the Seahawks shut out the Bears.

SAN FRANCISCO 49ERS

Last time out: Cardinals 47, 49ers 7

Record: 1-2 overall, 0-1 in division

Snapshot: Quarterback Colin Kaepernick threw a pair of pick-sixes in the first quarter and the Cardinals racked up 28 points before San Francisco got on the board. Kaepernick finished 9-of-19 for 67 yards with no touchdowns and four interceptions.

Notable: After allowing only a field goal in a season-opening win against the Vikings, the 49ers have given up an average of 45 points the past two weeks in blowout losses to the Steelers and Cardinals. Cardinals quarterback Carson Palmer finished the game 20-of-32 for 311 yards with two touchdowns and an interception and the 49ers couldn't stop the ground game, either, as running back Chris Johnson had 22 carries for 110 yards and two scores.

Quotable: "Very hard to see myself go out and play like that and hurt this team the way I did. I nullified all the efforts of every player on the field today." – Kaepernick after his poor performance

Key stat:29. The number of yards for the 49ers' leading receiver, tight end Garrett Celek.

Next up: The 49ers host the Packers on Sunday in Week 4

SEATTLE SEAHAWKS

Last time out: Seahawks 26, Bears 0

Record: 1-2 overall, 0-1 in division

Snapshot: The Seahawks led only 6-0 at the half but eventually overwhelmed an overmatched Bears team. Wide receiver Tyler Lockett returned the opening kickoff of the second half 105 yards for a touchdown and the Seahawks piled on from there.

Notable: Seahawks backup running back Thomas Rawls had 16 carries for 104 yards in place of an injured Marshawn Lynch. Bears backup quarterback Jimmy Clausen, playing for an injured Jay Cutler, finished 9-of-17 for 63 yards. Chicago punted on all 10 of its possessions.

Quotable: "You want to suffocate a team. It's big for our defensive staff, for our players, for everybody. It sends a statement." – safety Kam Chancellor on the shutout, in his first game back since ending his holdout

Injury update: Lynch had five carries for 14 yards before leaving with a hamstring injury, but coach Pete Carroll said it's not a serious injury.

Next up: The Seahawks host the Lions on Monday Night Football in Week 4

ST. LOUIS RAMS

Last time out: Steelers 12, Rams 6

Record: 1-2 overall, 1-0 in division

Snapshot:  The Rams' offense struggled for a second straight week, amassing only a pair of field goals and failing to put together a late game-winning drive. Their final effort ended when Kenny Britt's first-down catch on fourth-and-5 was ruled incomplete on replay review.

Notable: Steelers quarterback Ben Roethlisberger was knocked out of the game with a knee injury in the third quarter and was replaced by Michael Vick. The Rams' defense held a potent Steelers team in check but didn't get enough help. Kickoff was delayed 26 minutes because of a small fire near the south end zone caused by pyrotechnics during the Rams' player introductions.

Quotable: "Six points isn't going to win you a whole lot of games. We're averaging eight points a game the last two weeks, and that's not going to get it done for you. That's my biggest area of concern." – Rams coach Jeff Fisher

Key number: 9. Rushing yards for Rams first-round draft pick Todd Gurley, on six carries, in his NFL debut.

Next up: The Rams travel to play the Cardinals in Week 4
