According to Matt Barrows the 49ers are going to sign former Cardinals and Steelers defender Clark Haggans. Haggans was released on Friday and will sign with the team Sunday pending a physical.
Currently the 49ers have only three outside linebackers, so adding Haggans will give them some more depth on the line and give Brooks, Haralson and Aldon Smith rest from time to time.
Haggans started 16 games at left outside linebacker for the Cardinals last season, finishing with 30 tackles and three sacks.
Who is released in favor of Haggans is anybody’s guess…
