San Francisco also signed former Bear Jim Flanigan. The defensive tackle signed a two-year, $1.4 million contract.
Flanigan played seven seasons with the Bears after arriving as a third-round pick in 1994. The Notre Dame product led the club in sacks three times, including a career-high 11 in 1995. He was released last April after the Bears signed 300-pound-plus free agent run-stuffers Ted Washington and Keith Traylor.
Flanigan, a Green Bay native, recorded 46 tackles and 4½ sacks last season with the Packers.
