Jacobs becomes the second player formerly of the Super Bowl winning Giants to sign with the 49ers, the same 49ers the Giants ousted in the NFC Championship game. Wide receiver Mario Manningham signed a two-year deal with the team last week, joining a corps that includes newly signed Randy Moss, Michael Crabtree and Ted Ginn, Jr.
The Giants released Jacobs, who was scheduled to earn $4.4 million in salary for 2012, earlier this month rather than pay him a $500,000 roster bonus. Jacobs had been unhappy with his role on the Giants until after the team's Super Bowl XLVI win over the New England Patriots when he said that he wanted to remain in New York.
Now, he will get a chance to work in tandem with franchise runningback Frank Gore and rebound from a 2011 season in which he rushed for only 571 yards, his lowest output since 2006.
