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, according to ESPN.
The 6-year-old fan couldn’t understand why Jacobs was leaving the Giants and sent him a letter that read, "So you could go to the Giants, here is my money. Love, Joe." His mother had earlier explained the switch by saying, "The Giants didn't have enough money to keep him."
In his tweets, Jacobs posted a picture of the note and money and wrote, “The kid thought the giants didn't have enough money to bring me back, so he sent me 3.36 cent to come back it was the best ever. I almost cried, I am still trying to hold it in. I may have to pay him a surprise visit.”
The two-time NFL champ 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 October, The player told Men's Fitness magazine that he was not happy with his role with the Giants and he didn't think he'd be returning 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, according to ESPN.
