Metairie, LA -- (Sports Network) - The New Orleans Saints have signed free agent defensive end Anthony Hargrove.

Hargrove, a four-year veteran, will give the team depth at the position for the start of the season. Will Smith and Charles Grant have been handed a four- game suspension, but it remains on appeal in federal court.

Over his four seasons in the NFL, Hargrove has 134 tackles and 10 1/2 sacks in 57 games with Buffalo and St. Louis.

The 25-year-old Hargrove has violated the NFL's substance-abuse policy three times. After being suspended for all of 2008, he was reinstated this year.

To make room on the roster, the team released defensive end Josh Savage.
