The San Francisco 49ers agreed to a one-year contract with former New York Giants running back Brandon Jacobs, a league source said Wednesday.

Jacobs is the second former Giant to join the 49ers this offseason, following receiver Mario Manningham, who signed a two-year contract last week. The Giants beat the 49ers in the NFC Championship Game last season.

In San Francisco, Jacobs will pair with starting running back Frank Gore.

The Giants released Jacobs earlier this month rather than pay him a $500,000 roster bonus to go along with the $4.4 million he was due this season.

Jacobs, who turns 30 in July, had an up-and-down 2011 with the Giants.

Playing behind Ahmad Bradshaw, Jacobs rushed for only 571 yards in 2011, his lowest total since 2006, and was booed at times by New York fans.

In October, Jacobs told Men’s Fitness magazine that he was unhappy with his role and that he didn’t think he’d be back in 2012.

However, after the Giants’ 21-17 win over the New England Patriots in Super Bowl XLVI, Jacobs said he wanted to remain in New York.
