The Green Bay Packers did something against Colin Kaepernick Sunday they hadn't done in their first three meetings - contain him.
Kaepernick was sacked six times by Green Bay, threw an interception, and was limited to just 196 yards of total offense in a 17-3 Packers win.
"I feel like you can't get caught up in what's happened in the past, because there are so many variables there you know," defensive coordinator Dom Capers said. "I was pleased to see our guys go out and do the things we talked about."
Packers head coach Mike McCarthy called it his team's best defensive effort of the season, but was already looking ahead to Week 5 during a news conference held Monday at Lambeau Field.
"It's something we can build off, but we have a whole different opponent coming in here, the St. Louis Rams and the way they're able to threaten us, and that's what we are locked in to."
The Rams (2-2) handed Arizona its first loss of the season on Sunday thanks to a big day from rookie running back Todd Gurley, who rushed for 146 yards in a 24-22 win.
Kickoff for Sunday's game at Lambeau Field is set for 12 p.m.
