Their first 2012 matchup isn't until Week 8, but already these NFC West rivals are competing.
Arizona recently prevailed over San Francisco in a waiver claim for Jamaal Westerman, an outside linebacker released by the Miami Dolphins on the reduction to 53-man roster limits. Westerman, 27, gives the Cardinals a fourth outside linebacker for their 3-4 defense.
The 49ers are turning to the Cardinals' cut list for help at the position. Clark Haggans, released by Arizona at the 53-man deadline, plans to sign with the 49ers, Matt Barrows reports. Haggans, 35, will serve as the fourth outside linebacker in the 49ers' 3-4 scheme.
Haggans has one sack in eight career games against the 49ers. He has 46.5 career sacks, including a career-high nine with Pittsburgh in 2005. Haggans started all 16 games with Arizona in 2011.
