Flanigan, who played for the veteran's minimum of $500,000 last year, reportedly signed a two-year deal with San Francisco that could be worth as much as $2 million if he reaches performance incentives. He received a $100,000 signing bonus and will have a 2002 base salary of $650,000 that could go as high as $1 million with incentives.
Flanigan was one of the top defensive tackles still available on the open market. A third-round pick by Chicago in 1994, the 6-foot-2, 290-pounder has 45 career sacks and also has demonstrated he can be stout against the run.
Flanigan visited Jacksonville on May 3 and the 49ers a few weeks later. He will challenge defensive tackle Reggie McGrew for a starting spot on the defensive line.
