Jaguars sign DT Henderson to six-year extension
Financial terms were not disclosed.
Henderson was eligible to become an unrestricted free agent after the 2006 season.
Since the start of the 2005 season, the Jaguars signed defensive end Reggie Hayward to a five-year contract and re-signed defensive tackle Marcus Stroud, safety Donovin Darius and cornerback Rashean Mathis to multi-year deals.
The Jaguars may have the best tandem of starting defensive tackles in the NFL with Henderson and Stroud. Henderson led all AFC interior defensive linemen with 70 tackles last season and added three sacks.
A first-round pick in 2002, Henderson was named to the Pro Bowl for the first time in 2004 when he recorded career highs of 98 tackles and 5 1/2 sacks.
