As part of his recent contract agreement with the Bills, running back Fred Jackson will only earn $3 million in guaranteed money. That $3 million comes in the form of his signing bonus, not another penny is guaranteed. Jackson also gets a $100,000 roster bonus on the fifth day of the league year (which he may have already received), along with a $100,00 workout bonus. He's due to earn a base salary of $2.205 million in 2012. He'll get an extra $100,000 if he makes it to the Pro Bowl. Next year, Jackson is due to receive a base salary of $2.15 million, along with a roster bonus of $300,000 on the fifth day of the league year.
