FOXBORO -- According to the National Football League's Player's Association, Wilfork's five-year, $40 million contract includes an $18 million signing bonus and a base salary of $750,000 in 2010; $765,000 in 2011; $4.5 million in 2012; $6.5 million in 2013; and $7.5 million in 2014, with the base salary of the first three years all guaranteed.

His contract also includes weight bonuses. Wilfork must stay at 325 pounds or below, he said. The bonuses are as follows: $150,000 in 2010; $135,000 in 2011; $300,000 in 2012; $300,000 in 2013 and $300,000 in 2014.

In addition, Wilfork can make up to $800,000 in workout bonuses, including up to $100,000 in 2010 and 2011; and $200,000 in 2012-14.

"I never have a problem being at my weight," Wilfork said. "It's really not a big deal. Every big guy in the league that's a nose tackle/defensive lineman, that are bigger guys, all have this in their contract, so there's nothing in this contract that's unfair to me.

"I think with the contract, when the time presented itself, I think we both buckled down and we both worked hand in hand together to try to get this deal done, in which we did. There's nothing in this deal that I regret - not at all. If I had to do it all over again, I would probably just do it sooner."

Wilfork is now the highest-paid nose tackle in the NFL which is a testament to how important he is to the team.
