Jim Flanigan

A busy day for the 49ers personnel department as the team announced the signing of free agent defensive tackle Jim Flanigan to a two-year contract and also acquired quarterback Cade McNown from the Miami Dolphins for a conditional seventh-round pick in 2003.

San Francisco's first dive into the post-June 1 free agent pool resulted in the signing of Flanigan. A former Chicago Bear and Green Bay Packer, Flanigan also was a college teammate of Bryant Young at Notre Dame.

His first seven NFL years were spent in Chicago where he recorded a career-high 11 sacks in 1995. He spent last season as a member of the Packers where he recorded 46 tackles and 4.5 sacks in 16 games.

The eight-year veteran has 45.0 career sacks and has played in 124 games. He also has four receiving touchdowns in his career.

"I think Flanigan will stir things up at defensive tackle," said Terry Donahue. "He brings competition to the position and that competition is healthy."

Flanigan joins a 49ers defensive line that has two starters in Dana Stubblefield and Young, along with veteran backups Sean Moran, Reggie McGrew and rookie Josh Shaw.

"He's a veteran, a real pro," added Donahue. "He's got a great work ethic and we're trying to bring in as many guys with great work ethic and committment to the game as we can."

The two-year contract includes a $100,000 signing bonus and a base salary of $650,000.
