A league source tells us that the Jacksonville Jaguars have signed defensive end Paul Spicer to a two-year contract extension.

The deal is worth $8 million, and it puts Spicer under contract through 2010.

Spicer, 32, is a nine-year veteran.  He was due to earn $2.5 million in 2008, the final year of his contract.

In 2007, his eighth year with the Jags, Spicer appeared in 15 games, starting 12 of them.  He’ll likely be counted on to provide leadership and depth if/when rookies Derrick Harvey and Quentin Groves develop, and the magnitude of the salary indicates that Spicer will still be a key component of the rotation.
