A breakout 2007 campaign for New York Giants' backup defensive end Justin Tuck will on Friday become a break-the-bank season for the three-year veteran. Tuck and the Giants reached agreement Thursday on a five-year contract extension that runs through the 2013 season, has a maximum value of $30 million, and includes $16 million in bonuses. Barring any last-minute glitches, the final details of the deal will be completed on Friday, and the contract will be officially executed. The extension was first reported late Thursday by the Newark (N.J.) Star-Ledger and confirmed for ESPN.com by league sources.
